If you are using Outlook 2010 beta and the Office Outlook Connector, you’ll no doubt notice that you have multiple folders called “News Feed”, News Feed 1”, etc. You’ll also notice that even after you delete them, the folders keep coming back.
To prevent this from happening, disable the Outlook Social Connector add-in.
1. Open Outlook
2. Click File –> Options
3. Click Add-Ins
4. At the bottom where it says Manage: COM Add-ins, click Go
5. Uncheck the Microsoft Outlook Social Connector box, and click OK.
Close out of the options dialog, and then restart Outlook.
Hopefully this bug will be fixed in a later version of the software.
