Outlook Office 365 System Folder Names appear with 1
May 11, 2016 2 Comments
After an Office 365 migration I had noticed I had some duplicate folders in my Outlook. The duplicate folder appeared with a 1 next to the folder name, and what’s worse it was on the ‘System Folders’ like Junk Mail or RSS Feeds.
you might be forgiven for thinking, so what? well indeed, but it was annoying the hell out of me and this is my website, so there you go..
I tried numerous times to remove them, or delete them, and replace them with new folders. Of course none of this worked.
I even used MFCMAPI to do ‘Hard Deletes’ on these folders with no luck, because even when they were deleted they would just return on subsequent reloads of Outlook.
I hadn’t noticed, or more accurately thought to try and rename the folder within MFCMAPI because I was too focussed on getting rid of the RSS Feeds folder, which I have hated since Outlook 2003.
Just navigate to the folder, find the Display Name field (PR_DISPLAY_NAME) Amend the name, and click OK. The change is reflected immediately in MFCMAPI and Outlook.
Hopefully this will save you many hours of restless OCD Driven sleep.
