There are many reasons you would wish to use MFCMAPI to conceal, relocate, or destroy a folder. For example, to re-hide a folder that shouldn't have been displayed in the first place (like the "News Feed" folder) or to conceal "special folders" for functions you do not use. In the uncommon event that one of the default Outlook folders becomes a subfolder of another default folder, such as the "Inbox" folder being listed under the "Deleted Items" folder, MFCMAPI also enables you to relocate the default Outlook folder back. Invisible folders can also be "revived" using the procedure in this article. When utilising a Search Folder or Instant Search, for example, these invisible folders still appear (even after rebuilding your Search Index), or you receive an error.

MFCMAPI is a sophisticated tool. Through a graphical user interface, it offers access to MAPI stores using Microsoft's public APIs. It is a free program that Stephen Griffin from Microsoft has released as open-source on GitHub.The concealing option is favoured over the removing method for default folders (RSS Feeds, Junk Email, Suggested Contacts, etc.). This facilitates restoration and decreases the likelihood that the folder will reappear or that Outlook will crash as a result of the missing folder (as the hidden folder is still accessible programmatically).

If you can't delete a folder via Outlook and you're quite certain you don't want it anymore, delete it via MFCMAPI. Unhiding a folder once more is quite easy.
