Encrypted files and emails are used as an extra security measure, most likely when you are using a computer for work or any kind of business communication. The issue you may run into with encrypted files down the line is actually finding those files using desktop search or Outlook search. Usually the encryption will make the files or emails completely unsearchable. Continue reading to discover more about encryption, and if and how you are able to index encrypted files.
- A warning will pop up saying “Cannot verify data security”. If you are sure you have full volume encryption used for the location of the index, click Continue.
- Click OK.
This will work the same for Windows 7,8, or 10, but please note that if you use a third party program to encrypt the system’s drive, they will not be supported. Windows will only support files that are encrypted using EFS (Encrypting File System). You should also encrypt the location of your index, so that if someone were to access your computer they couldn’t take any data from the index.
Clear Signed Emails
Clear-signed emails are a way to encrypt email messages for security purposes. Clear Signed email messages cannot be found using Outlook Search. The way the body of a clear-signed email is packaged through Outlook makes the text unsearchable. It does not matter if you use Advanced searching, or instant search in Outlook—Clear signed messages cannot be found. Signing and encryption technology can seem really confusing; see Understanding Public Key Cryptography for more information on the subject.
While some encrypted files may be indexed by Windows Search, Encrypted emails are another ball game, and will be hard to find through Instant Search, or Outlook Search.
A Workaround for Encrypted Emails
If you desperately need to search for encrypted emails and their contents, the best workaround for this is to create a search folder that only holds encrypted mail. This way, you’ll still have to search for the email manually, but you can do so without having to search through all of the mail in your inbox. You can do this by creating a search folder with advanced filters:
- Right click on Search Folders at the bottom of your Mail navigation pane
- Click New Search Folder
- Double click on Create a custom Search Folder at the bottom of the list
- In the window that pops up, click Criteria…
- In the Advanced tab, under Define more criteria: click Field > All Message fields > Message Class
