Solution for "MAPI: This is not supported"

MAPI means Messaging Application Programming Interface, which is related to emails, especially with Microsoft Outlook and Microsoft Exchange.

1. Try to repair MAPI by executing "C:\Windows\System32\fixmapi.exe".

2. Try to restart all your opened Office programs (Word, Excel, Outlook, PowerPoint, etc.)

3. Check if you have 2 versions of Office installed at the same time. If so, keep only the latest version by uninstalling the older one, and repair your most recent Office version.
