I've been running Mac Outlook 2011 for well over a year now with all my inboxes (1 Exchange, 1 Pop, and 4 IMAP) properly Grouped (preference>general>group similar folders, such as inboxes, from different account.... CHECKED). A few days ago, following a recent sw update (I'm not sure if that is related), all but one (IMAP) of my email folders Grouped under "Inbox" have started disappearing.
If I ungroup the folders, all the inboxes reappear (as they should) under their respective accounts with no issues.
When I restart Outlook the Grouping of Inboxes works again for a few minutes before folders vanish again!
I have uninstalled and reinstalled Office again, and installed all update patches, but the problem persists.
I checked all forums but could not find anyone with a similar problem. Please help!
