Your sources. One search.
The answer might be in an email, a network folder or an archive from five years ago. With Lookeen, you don't have to know where to look. Bring files, mailboxes and archives into one searchable index — without moving the originals.
Connect the places your knowledge lives
From your own Outlook archive to company-wide file shares: choose the sources you need, then search across them together.
Files, file servers & network drives
Turn scattered folders into answers. Search documents on local drives and network shares by content, not just by name. Lookeen Server brings company file shares into one central, permission-aware index.
Outlook, PST & OST archives
Find the conversation, then the attachment. Lookeen Desktop reads PST and OST files directly, even with Outlook closed. Lookeen Server indexes individual PST archives or entire PST directories, without attaching them to Outlook.
Microsoft 365 & Online Archives
Bring current email and years of archived knowledge into the same search. Search Exchange Online mailboxes you have access to, including shared mailboxes and Online Archives. Lookeen Server indexes centrally and takes accounts and permissions from Entra ID.
Exchange Server on premises
Keep your mail infrastructure. Add the mailboxes on your own Exchange Server to your search. Lookeen Server connects centrally, including shared mailboxes and Public Folders, alongside your files and archives.
OneDrive
Find cloud documents alongside the email that gives them context. Lookeen Server indexes OneDrive through Microsoft Graph, bringing Microsoft 365 files and on-premises sources into one search experience.
Kerio Connect
Coming soon · Lookeen Server only
Your search should fit your mail platform. A dedicated Kerio Connect connector is coming to Lookeen Server, extending the sources you can bring together in your central search. Not yet available.
Microsoft 365 Online Archives — without EWS
Microsoft is retiring Exchange Web Services (EWS) in Exchange Online, part of Microsoft 365. Lookeen Server indexes Exchange Online mailboxes and Online Archives through Microsoft Graph, so your archived email stays searchable beyond that transition. The retirement applies to Exchange Online, not Exchange Server on premises, which continues to use EWS.
Millions of files. Still one place to look.
Lookeen Server is built to index millions of files and documents across your organization's sources. Instead of opening each folder or mailbox for every search, your team searches a central index — with results filtered by access permissions.
Grow beyond a single drive
Bring file servers, mailboxes and years of PST archives together. Size the server and index storage for your data volume, content and indexing workload.
Keep fresh content findable
Set indexing schedules to suit each source: frequent updates for active shares, or a one-time run for a closed archive.
Share search, not access
Lookeen Server respects permissions from your file system, Exchange and Microsoft 365. A central search doesn't turn private content into shared content.
Go beyond file names. Find what's inside.
Search the content of Office documents, PDFs, emails and attachments, alongside many more supported formats. The invoice inside an email matters just as much as the document on a drive.
OCR: make scans searchable
Scanned contracts, receipts and image PDFs don't have to be search blind spots. Optional OCR recognizes their text and adds it to the index without changing the originals. With Lookeen Server, recognition can run locally with Tesseract; cloud OCR is optional and requires explicit configuration.
Vision — coming soon
Text is only part of the picture. Vision is coming to Lookeen to extend how visual content can be made searchable, beyond text recognition alone. Not yet available; supported capabilities will be detailed at launch.

Supported sources by product
Lookeen Server indexes centrally for your organization, with permission-aware results. Lookeen Desktop indexes your own data on your PC. Here's how the supported sources compare.
| Data source | Lookeen Server | Lookeen Desktop |
|---|---|---|
| Files, file servers & network drives | Central file shares and drives | Local, external and mapped network drives |
| Outlook, PST & OST archives | PST files and directories; no direct OST connector | Outlook, PST and OST files |
| Microsoft 365 & Online Archives | Mailboxes, Online Archives and shared mailboxes | Accessible mailboxes, including shared mailboxes, and Online Archives* |
| Exchange Server on premises | Mailboxes, shared mailboxes and Public Folders | Accessible mailboxes, including shared mailboxes, and Public Folders |
| OneDrive | Direct connector through Microsoft Graph | Locally synced files through the file connector |
| Kerio Connect | Coming soon | Not supported — Server only |
* Online Archive search requires Lookeen Desktop Business or Premium. The Microsoft Graph capability described above refers to Lookeen Server. A locally synced OneDrive folder is indexed as files; it is not a direct cloud connector in Lookeen Desktop. Coming-soon features are not available in the current release.
Frequently asked questions
What happens to your data and which sources you can connect.
Do I have to move my data into Lookeen?
No. Lookeen builds a search index from the sources you connect. Your original files, emails and archives stay where they are. With Lookeen Server, the central index lives on your own infrastructure.
Does Outlook have to be running?
No. Lookeen Desktop reads PST and OST files directly, even when Outlook is closed. Lookeen Server can index PST archives without connecting them to Outlook.
Can I connect Kerio Connect today?
Not yet. The Kerio Connect connector is coming soon and will be available for Lookeen Server only, not Lookeen Desktop. Contact us to discuss your requirements.
