Turn Off Clutter in Office 365 and Delete Clutter Folder from Outlook

Unfortunately Microsoft’s documentation team can never keep up with Office 365 development team (they don’t seem to be on speaking terms either), so its very rare to actually find accurate instructions for common tasks.  So it is with get rid of the diabolical ‘Clutter’ feature of Office 365 (AKA ‘a slightly less sensitive Junk Mail Folder’), here’s how you do it as of June 2016 (I’ll try and update as MS shift Office 365 around).

How do I Disable Clutter in Office 365?

  • Sign in to Outlook Web Access (the Office 365 Webmail for all intents and purposes) at http://mail.office365.com
  • In the top right hand corner, click the small cog icon, a side bar will appear.
  • Near the bottom of the sidebar is a heading saying My App Settings
  • Click Mail underneath this, you will be take to the Mail Options page
  • On the left menu, underneath the Automatic Processing menu item, click Clutter
  • Uncheck the box that says Separate items identified as clutter
  • Click the Save button at the top of the page (I think its weird having to go back to the top of a page to hit save).

How do I Permanently Delete Clutter Folder in Outlook?

Unfortunately Microsoft are so keen on Clutter that if you delete it, it just comes back! I’m happy to say however that a Microsoft engineer called Stephen Griffin has created a low-level and powerful (therefore dangerous – use carefully) mailbox editing tool called MFCMAPI.
Here’s the process:

Identify if you are running a 64bit or 32bit version of Outlook, a good guide can be found here: http://www.sperrysoftware.com/Email-Tools/how-to-tell-if-you-have-32-bit-or-64-bit-outlook/

Download the MFCMAPI tool from the free download page: http://mfcmapi.codeplex.com/releases/view/617103

Unzip the file and double-click executable (it doesn’t require installation – its a standalone program)

Click OK to accept the usage notes

From the top menu click Session
