This feature has been working fine up until this week. Now I can add a folder but cannot rename it on my MACbook Pro. When I click on "Untitled Folder" or use the Rename Folder option in the drop down menu; it jumps immediately back to "Untitled Folder" without allowing any edits.

Please advise? Thx
I'm using Outlook 2011 (14.2.2).  I've discovered that I can drag messages to that folder but still can't rename it.  When I select rename it looks like I'll be able to rename it but the folder name is automatically un-highlighted to quickly. 

The rename of the online "Untitled Folder" is successful via Outlook Web Mail or from Outlook 2010.

Thank you in advance.
