What, though, about archive PST files you may have flying around? What if you want to grant some people access to them — or parts of your Outlook even?
Outlook, quite conveniently, lets you assign a password to an individual PST file.
Protect Access to an Outlook PST File with a Password
To add password protection to a PST file in Outlook:
- Select Go | Folder List from the menu.
- Click on the root item of the desired PST file with the right mouse button.
- If you want to protect only certain email folders with a password, you can move them to a newly created PST file and assign a password only for that file.
- Select Properties for... from the menu.
- Click Advanced....
- Now click Change Password....
- Enter the desired password under both New password: and Verify password:.
- If a password had already been set for the PST file, enter that phrase under Old password:.
- If you assign a password to a previously unprotected PST file, leave the Old password: field blank.
- To remove the password from a PST file, enter it under Old password: and leave both New password: and Verify password: blank.
- Click OK.
- Click OK again.
- Now click Cancel.
