I want to buy a License Key for version 8, instead of Lookeen 10. Is that still possible?

Go to “Tool” -> “Folder options…” -> Tab “View” and choose the option “Show hidden files, folders, and drives”. Now go to C:Users[YOUR PROFILE NAME]AppDataLocalLookeen[YOUR OUTLOOK PROFILE] Back up the folder “Index” and paste it to the same location when necessary.

Registration & Installation:

What does a Lookeen lifetime license include?

Purchasing a lifetime license for any Lookeen product entitles you to use the Lookeen product for which the license was purchased forever. It also entitles you to free updates to that product for as long as we continue to develop it (eg. versions 8.X to 8.Y).A lifetime license does not entitle you to receive a free license for any new Lookeen products. Any upgrade that requires a new license key to be purchased is considered a new product.For example, just as owning valid TeamViewer 10 license does not entitle you to a free copy of TeamViewer 11, a valid license for Lookeen 8 does not entitle you to receive a free license for Lookeen 10.

If you need an MSI file for your installation, please contact us here.

Is it possible to choose those users in a company-wide installation which will be able to use Lookeen?

By applying this GPO to certain users or user groups you can prevent those from using Lookeen or you can set exceptions from the GPO to restrict the use of Lookeen to certain users or user groups.

How can I perform a silent (unattended) installation?

Installing Lookeen using the .exe installer, a silent installation can be triggered by invoking the parameters

This is particularly helpful when deploying Lookeen to several users as no further input is required.

The operator /silent will hide the Lookeen Wizard but still display installation progress, whereas /verysilent will hide these windows altogether.

Further information on these parameters as well as a few others can be found here: http://unattended.sourceforge.net/InnoSetup_Switches_ExitCodes.

Setup & Usage:

Can I run Lookeen as a pure Outlook plugin like Lookeen 8?

Yes you can: During the installation you have the possibility to choose whether you want to install Lookeen as a pure Outlook® plugin. Just enable the according option on the setup screen.If you chose to install Lookeen as complete desktop search (by not enabling this option) and want to change this after installation you don’t need to reinstall Lookeen: Create an empty text file and name it olpluginonly.bin Make sure it is not named olpluginonly.bin.txt (on saving, choose “all files” as file type)! Then put this file into the installation directory of Lookeen (you need administrative rights for this). Close Lookeen and restart Outlook®. From now on, Lookeen will start and end together with Outlook® and you can’t run Lookeen standalone anymore, the functionality however won’t be affected in any way!

Are the Lookeen Shared Index feature and the Lookeen Server feature still available? There are no according tabs in the options anymore.

Of course those features are still included! Lookeen now displays all index sources on a single tab. In the options window on the index tab, click “Add Store” and in the next window, double click on the kind of archive you want to add. A Lookeen Shared Index as well as a Lookeen Server can be chosen here.

I work on two workstations and use Lookeen on both of them. Do I need a second license?

The Lookeen licensing depends on the amount of users and workstations. Please have a look at the EULA for details.

I want Lookeen Desktop Search to index only during a given time period. Is that possible?

Sure. On the Options tab “Index Schedule” you can specify, at which times you want to allow Lookeen to perform the indexing. If you need your full system resources at a given time you can also specify when Lookeen must not index.

How should I execute the index if my archives and file stores are huge?

You can certainly index all archives and file stores in one session – that’s no problem. It could take a while and sometimes your performance will be affected. In this case we recommend indexing your archives and file stores step by step.

Can I close Outlook during the indexing process?

Yes, you can. Lookeen Desktop Search remembers where you stopped and the next time you start the index again you don’t have to start from scratch!

Can I search a search term in a range of date?

Yes, please take a look at our help, section “Search Words & Query Syntax” – there you find all tips and tricks you need.

Can I search partially? Does Lookeen support search terms with only part of a word?

Yes, Lookeen supports the wildcards * and ?. * represents an arbitrary amount of characters whereas ? stands for a single character.

Is there a preview of the search results?

Lookeen Desktop Search features an integrated preview window. You can choose where you want to show the preview and several other settings as well. Thanks to the multiple highlighting your search terms will be colored differently in the preview.

I want to select and copy parts of the preview. On right clicking nothing happens.

In the pure text preview, the context menu is disabled for technical reasons. But you can select a part of the text and press Ctrl-C to copy it. In the preview modes “Show Original”, the context menu is available.

In which languages is Lookeen Desktop Search available?

It is available in English and German. The default language is your default OS language. However, you are able to customize the language in: Options > System > Language.

Can I switch off the Lookeen Desktop Search add-in in Outlook without uninstalling it?


  • 1. Outlook® 2003
    Only by editing the registry entry of the Outlook subkey or by uninstalling because it isn’t listed as an AddIn.
  • 2. Outlook® 2007
    Go to “Tools” in your Outlook® menu and then “Trust Center”. Within the Trust Center go to “Add-Ins” and “COM-Add-Ins” and disable Lookeen there.
  • 3. Outlook® 2010, 2013, 2016 and Office 365
    Go to “Options” in the file menu and switch to “Add-Ins”. Choose “Go to” while “COM Add-Ins” are selected and disable the Lookeen checkbox.

This way you can activate Lookeen Desktop Search again if you want to.

What do I have to consider when I use Lookeen Desktop Search for the first time?

After installing Lookeen Desktop Search, you will be asked to go through the “Lookeen Wizard”. Only a few clicks are needed to configure Lookeen. Then your email archives and file stores will be indexed. Only after this has been finished, you will get really reliable search results with the Lookeen search.

Can I save search queries which I use often?

Yes. Enter the desired search parameter and execute your search. After that go to the menu bar to “Favorites” -> ”Add favorite…”. Please see the section “Main Menu -> Favorites” in the Lookeen help for further details.

Is there a possibility to get a special offer for volume licenses?

Here you will find the price list of Lookeen Desktop Search. For volume licenses we can make you a special offer. For that please refer to sales@lookeen.com.

Categories are not shown in the search results and I cannot search for categories. What shall I do?

To index categories of Outlook® items you have to activate this in the options. Go to “Options” -> ”Outlook” and activate “Index Outlook Categories”. After that you have to rebuild your index from scratch. With a right click in the search result window you can customize you columns and add “Categories” there.

If I add a new Outlook archive, do I have to add it manually to Lookeen?

Usually you have to. In the option tab “Index” you need to click “Add Store” and in the next window double click “Discover new Outlook® Archives”. Furthermore in “Options”->”Outlook®” you have the possibility to choose “Detect new Outlook® archives when Outlook® starts”. With this option, the new archives will be added automatically.

Known Cases:

Lookeen keeps telling me it cannot connect to Outlook. How can I solve this?

This happens when you run Outlook® as administrator and Lookeen isn’t set up the same. Right click C:Program FilesAxonicLookeenLookeenDesktopSearch.exe (on 32 bit operating systems) or C:Program Files(x86)AxonicLookeenLookeenDesktopSearch64.exe (on 64 bit operating systems) and select Properties. On the compatibility tab check the “Run this program as an administrator” option.

I have set an external index. However Lookeen matches no content of the external index. Why not?

This might be due to the fact that no UNC path has been set. If you choose an external index source, set this index not via local path (My computer) but rather via network (My network).Important Advice: Lookeen saves no active directory rights or other access privileges in the generated indices. Adding a user to the shared Lookeen index allows the unrestricted search in this index. When the Outlook profile which creates the shared index has more rights as the user who adds this index, the user gets access to all files, maybe to files he doesn’t have the rights for. Please make sure whom you allow to search in which shared index and where you set your index path.
If you would like to create an index, where every indexed item is only accessible through Windows Access Rights, then the “Lookeen Server” is for you. Please write to us at: sales@lookeen-server.com.

Apparently, the search results of Lookeen just show the matches of the last few months. Or definitely not all expected search results, respectively. Why could this happen?

This happens usually if you have a lot of hits. This is caused by the default settings which only show you the latest 5000 matches. You can change this limit in the options at the tab “Search”. You can also restrict your query with additional terms to make your search more efficient.

I have problems to use the automatic updater. It doesn’t work. I’m not able to get the update. What should I do?

First, please uninstall Lookeen Desktop Search completely. Afterwards download the latest version here.

Are only the search terms saved by the Lookeen Desktop Search Favorites?

No. Lookeen Desktop Search saves the favorites as complex search queries. This means, that parameters like time-span or file extensions are also saved in the according favorite item.

The search term *.xls or e.g. *.doc does not display the required search results! What could I do?

Search with the term: xls instead of *.xls – now you can find the files easier. You can also use the extended search fields or expression search.

  • a) attachments: att:xls
  • b) files: fn:xls

Can I clear the search history?

Yes. Go in your search result window to “History”->”Clear history”.

Can I use Lookeen to search saved email (.msg) files?

Yes, .msg files are indexed per default.

Why can’t I find some attachments and file formats?

For special, less frequently used attachments (in Outlook) or file formats (on your network / local), there isn’t a so called “iFilter” or it is not installed on your system. But you can add more attachments in the Lookeen Options tab and by selecting add “index details” and then restarting the index to index these as well. If you want to add other formats to be indexed, you need the suitable iFilter on your system – you can get it here.

The index will stop incorrectly or Outlook will be shut down incorrectly during the indexing process or I’m not able to close Outlook correctly – what can I do?

This can have various reasons. Please open the Lookeen options and unselect the option “Index attachments” in the tab “Index details”. Is the indexer now running? It’s possible that you may either have a corrupted or unreadable attachment, which stops Lookeen to update or create its index.

  • 1. In most cases, it involves ‘PDF’ files that lead Windows 7 or 64bit systems specifically to crash.Install the free Adobe Reader from https://get.adobe.com/reader/ or alternatively for private users the PDFlib TET PDF IFilter at: http://www.pdflib.com/en/download/tet-pdf-ifilter/
  • 2. In some cases your .PST files are damaged, and you may consider using “scanpst.exe” to repair them. Further information can be found in the Microsoft knowledge base article.
  • 3. On older system it may further help to reduce Lookeen’s memory and CPU usage in the options:
    • a) “Index Details” tab – reduce the slider to like 20 – 30%
    • b) “System” tab – enable “Automatic cache-cleanup…”
  • 4. We have tested a program that performs daily PC maintenance and discards faulty registrations (for Outlook®) immediately. This led to disturbances in Lookeen and thus caused Outlook® to crash. After disabling the software, Lookeen now works without any problems.

Although I installed the latest version of Lookeen, I got the error message: “Lookeen has a problem opening an Outlook item.”?

In order to track moved or deleted emails, the origin- and the target folder have to be indexed. E.g. if you delete an email, the folder “Deleted Items” has to be in the index, too. If not, Lookeen is not able to know where the email goes to. Please check in Options>Index, if all affected folders (folders from or in which you are moving emails) are selected and in the index.
In some cases this can also be caused by interrupting the initial index, e.g. by abruptly closing Outlook® or crashes as well, so an item change can not be tracked and the linking is broken.
If you are searching for an item from a shared index, ensure that you have added the index as a UNC-path.

After reinstalling Lookeen it reports that my trial period is over and I have to buy it although I have already bought and registered it in the last version?

This might be caused by an older Lookeen install. To get another trial period, please contact us via support@lookeen.com.

I cannot search terms within PDFs, but in all other files – what’s wrong?

You need an iFilter to index the content.
Install the free Adobe Reader from https://get.adobe.com/reader/ or as an alternative for private users, the free PDFlib TET PDF IFilter http://www.pdflib.com/en/download/tet-pdf-ifilter/.Please Note: You should delete the index after installation and recreate it, so that the content of PDF files will also be indexed.

If I start Outlook 2003 after uninstalling Lookeen before, I get an error message concerning “extension…redemption.dll…could not be loaded or installed…”, what shall I do?

If you don’t want to use Lookeen any more, please do the following: In the Outlook® 2003 toolbar select “ToolsOptionsOtherAdvanced Settings” and uncheck “Redemption Helper Outlook® Extension”. Please take a look at the “Vista/Office 2007″ FAQ section for the adequate hint.

My Outlook seems to be idle in the online-mode (Exchange). What should I do?

Please quit the server request.

The toolbar of Lookeen Desktop Search can still be seen but some functions are limited. What do I have to do?

In that case your trial version of Lookeen Desktop Search has expired. 14 days have passed. To buy Lookeen Desktop Search, click here and follow the instructions. If you do not wish to buy Lookeen Desktop Search – which we would regret very much – you can uninstall it.

The toolbar of Lookeen Desktop Search cannot be seen in Outlook anymore, what should I do?

  • 1. The system may have switched off the Lookeen Add-In. To activate it again, do the following:
    Outlook® 2003
    In the ? menu, choose Info and select “Deactivated Elements”. Activate Lookeen there.
    Outlook® 2007
    In the ? menu, select “Deactivated Elements”. Activate Lookeen there.
    Outlook® 2010 / 2013 / 2016 / 365
    Go to File -> Options -> Add-Ins. On the drop down menu at the bottom, choose “Deactivated Elements” instead of “COM-Add-Ins” and click on “ Go to”. In the next window, select Lookeen and click on “Activate”.
  • 2. Maybe the system has switched off Lookeen in the Outlook® menu:
    Outlook® 2003/2007: Go to to “Extras” -> “Configure” and activate the Lookeen toolbar and/or tab again.
    Outlook® 2010/2013/2016/365: Go to File -> Options -> Customize Ribbon and activate the Lookeen toolbar and/or ribbon again.
  • 3. Finally you can run the diagnostic tool of Outlook®. Please go to Help -> “Office Diagnostics…” (Outlook® 2003) or “Start Diagnostics” (Outlook® 2007) and see if Lookeen is available again after this. Outlook® 2010, 2013, 2016 and Office 365 do an automatic repair on start.

On some searches I get hits, but in my search result window I cannot see any results. If I change the tab, then I can see my results. How can this be?

Lookeen Desktop Search remembers the last opened tab. If you had “Attachments” opened in your last search and the actual result has no matches in “Attachments, the tab “Attachments” is opened to you without any items.

Some of our networks are very slow. If Lookeen is indexing those networks, this lasts quite long. Can I exclude chosen network resources?

Yes. Go to “Options”->”System” and activate “Do not index if one of these (slow) networks is active”. Enter all desired Networks into the “Blacklist”. If one of these networks is active, you will be warned before Lookeen indexes it.

Although a network is active which is on the Blacklist, Lookeen indexes anyway if I start the indexer. Why?

Lookeen Desktop Search warns you, when an automatic indexing starts and a network on the Blacklist is active. But if you start the index manually, Lookeen assumes that you are aware of this fact.

We have ported all data of our company from Groupwise to Exchange Server. Are we able to index those data?

Lookeen also indexes data which has been ported from Groupwise® to Exchange® Server. However some fields of the data can get lost during the porting. We have no influence on that.

Sometimes Lookeen Desktop Search does not index attachments. Why?

To index the content of attachments and items like PDF-files, you need the according IFilter. For further information and links to the latest IFilter go to www.ifilter.org.

I cannot register Lookeen Desktop Search permanently. Why?

The User Account Control (UAC) can help prevent unauthorized changes to your computer. You will be asked for your permission when a task requires administrative rights, such as installing software or changing settings that affect other users. This may be the reason that you aren’t able to register Lookeen permanently. We don’t recommend turning off the User Account Control. If you turn it off, please turn it back on as soon as possible. Instead, change the control to “normal”

  • 1. Open User Accounts by clicking the Start button, clicking Control Panel, and click on User Accounts and Family Safety, (or just User Accounts, if you are connected to a network domain).
  • 2. Click on “Change User Account Control settings”. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
  • 3. Select the check box “Use User Account Control to help protect your computer”. Slide the slider to the 2nd from the bottom: “Standard – Notify me only when changes are made to the computer applications.” Then click OK.

I have problems to install Lookeen – the installation reports that it does not work or the installation causes an error message. What should I do?

  • 1. Sometimes you need to re-register Windows Installer (error code 2203): a) Press Starttaste+R to open the command prompt. Enter the following command and press the Enter key: msiexec /unregister b) Then register Windows Installer again by entering the following command, followed by Enter: msiexec /register
  • 2. In some cases you need to uninstall every “Windows Installer” version on your operating system and after that reinstall the Windows Installer 4.5 from here.

Office 2007:

I have problems finding Office 2007 files like .xlsx or .docx, what can I do?

In order to index the Office 2007 files, you have to do the following:

  • 1. Please check in Options>Preferences in “Files and attachments” if the needed files are listed. If not, add them manually, delete your index (in Options>Index) and rebuild the complete index.
  • 2. Please check if you have already installed the Office 2007 Service Pack 1 from Microsoft, if not, please download it from here.
  • 3. Please check whether you have already installed the latest iFilter Pack from Microsoft, if not, please download it from here.

Sometimes especially .docx files are not found anyway. Then go to your install folder (usually C:Program filesAxonicLookeen) and create a new text file. This file can be created without any content. Please name this file “docx.bin” and set up your index from the scratch.

I’m not able to uninstall Lookeen, why?

“Please run the setup.exe as administrator (to do so use SHIFT+Rightclick –> Run as…). Then select “Remove”.

If I start Outlook 2007 after I have uninstalled Lookeen before, I get an error message concerning “extension…redemption.dll…could not be loaded or installed…”, what shall I do?

Please go in Outlook 2007 to: Tools>Trust Center>Add-ins. Switch from “COM Add-ins” to “Exchange Client Extensions” and press “Go”. Uncheck the checkbox at “Redemption Helper Outlook Extension”. Press “OK”.

I can’t see Lookeen in Windows Vista/Outlook 2007 despite the fact that the installation was successful. Why not?

  • 1. First possibility is that Lookeen is not activated in the Add-In Manager. To change this, go to “Trust Center” in the Outlook menu. Select “Add-ins”. Under “Inactive Application Add-ins”, you should be able to find a Lookeen entry here. Select this and click on “Go To”, tick the box next to Lookeen and click on OK. Lookeen is now among the “Active Applciations – Add ins.”
  • 2. Second possibility: click on “Help” in the Outlook 2007 toolbar and then check “Disabled Items” – Lookeen must be enabled!
  • 3. Third possibility: go to Tools>Customize>Toolbars and mark the checkbox “Axonic Lookeen”.
  • 4. Another possibility is that the “User Account Control” (UAC) is deactivated. Please switch this on. Go to Start/Run, and type in “msconfig”. Click on enter. In “Tools”, look for the option “Enable User Account Control.” Mark this and click on “launch”. You’ll need to restart your computer.
  • 5. Eventually you can run the diagnostic tool of Outlook. Please go to Help -> Office Diagnostics…

I am not able to install Lookeen or I get an error code 2869 when trying to install Lookeen. What shall I do?

Please make sure before starting the installation that Outlook® has been completely closed (also check the task manager). In most cases, the error code 2869 no longer comes up when starting a Lookeen installation. If this was not the reason for not being able to install Lookeen, please try one of the following two solutions. Before starting to try the solutions given please check the following: Had the User account control been deactivated? Please activate this control by pressing Start and entering “UAC” into the search field. In the next window activate the UAC by setting the ruler to any setting but the lowest. After that you will have to restart your PC.

  • A 1. Try to uninstall the old Lookeen version (if not possible proceed with the point B)
  • 2. Delete the folder “Lookeen” in the directory C:Users[YOUR NAME]AppDataLocal (you have to enable in your Windows Explorer in Tools>Folder Options>View “Show hidden files and folders”!!)
  • 3. Delete the folder “Axonic” in directory C:Programs or in C:Program Files
  • 4. Start the Lookeen installation
  • B 1. try to delete Lookeen by following the steps described in solution A
  • 2. right-click on the setup.exe and select “Execute as administrator”


If I check the messages in the progress window during indexing, I can see some error messages – some folders or even whole archives cannot be indexed, why?

The PST file you’ve tried to index has to be repaired. Please use the tool “scanpst.exe” in order to repair your PST file – afterwards you’ll be able to index it with Lookeen Desktop Search.

What is a “Shared Index”, how does it work and why do I need it?

The Shared Index feature is included with the Enterprise Edition of Lookeen desktop search and enables the user to add external index sources. Imagine you have archived several pst-files in the last years. There have been no changes made to these archives, but you still need information out of them. Another common case for using the Shared Index is when you need the information from one source distributed to several users. The Shared Index is a feature of Lookeen to index data centralized. Afterwards, an optional number of users can add this index to their index-sources and search through it – even open items from this source. This makes the Shared Index to a powerful feature that preserves your indexing efforts and your system resources. Here is an explanation, how to configure a Shared Index:

  • 1. Create a new Outlook® profile
  • 2. Start Outlook® with this new profile – this will be from now on your “Shared Index” creating/updating profile.
  • 3. Add to this Outlook® profile the stores and archives you seldom want to change, the Outlook® archives you’re not really working with – the typical old stuff, archives, etc.
  • 4. In the Lookeen options, add these stores with “Index>Add Store>Microsoft® Outlook® Archive” and index them.
  • 5. Please note the index path which is displayed in Options>Index Details.
  • 6. Now close this Shared Index profile and start Outlook® with your “working/recent” profile.
  • 7. Here you can close all old ones of these aforementioned archives in Outlook®.
  • 8. Now go to the Lookeen options, add the stores you want to index with that profile – the ones you use every day (e.g. your recent mailbox) and index them.
  • 9. Afterwards go to the tab “Shared Index” and just add the path to your index which you have created with the other profile – with just 2-3 clicks!
  • 10. Now you’re able to search in both indexes. You can open items you’ve found with Lookeen out of the shared index WITHOUT being forced to open the archive in Outlook® too!!!

Important Advice: Lookeen saves no active directory rights or other access privileges in the generated indices. Adding a user to the shared Lookeen index allows the unrestricted search in this index. When the Outlook profile which creates the shared index has more rights as the user who adds this index, the user gets access to all files, maybe to files he doesn’t have the rights for. Please make sure whom you allow to search in which shared index and where you set your index path.
If you would like to create an index, where every indexed item is only accessible through Windows Access Rights, then the “Lookeen Server” is for you. Please write to us at: sales@lookeen-server.com or visit www.lookeen-server.com for more information.

I would like to create several Shared Indexes and provide them to different users or user groups. Is this possible?

Yes. By sharing the Shared Indexes with certain users or user groups within Windows, you can specify easily who shall access your indexes.

I need the Shared Index only every now and then. Is it possible to search it only if needed?

Above the column “Archive” in the search window there’s a dropdown menu where you can select the archives to search. Narrow down your search there.

How can I encrypt the directory in which my index is located in order to protect it from undesired access from other users?

Here is a guide from Microsoft® to encrypt folders.
