When trying to export email to a PST from FTK 6.2 you receive the following error messages even though you have Outlook installed:
Possibly MAPI is not installed correctly. Please install CDO or a 32-bit install of Outlook.
Install a 64-bit version of Outlook alongside FTK, and not a 32-bit version.
Note: According to the below article, a 32-bit version of Outlook is usually recommended to allow exporting to PST from FTK. However, in the situation where the error above is occurring with 32-bit Outlook, try using a 64-bit version of Outlook.
