An issue from 2011 seems to have come up again in 2014. I have a window in the bottom right hand corner of Outlook (2011 for Mac) that says "Updating message list" and it is stuck at ZERO / however many. (The number keeps going up.)

I can see the messages on my iPhone and they are NOT being delivered to Outlook. I have restarted both the computer and Outlook itself. Have also rebuilt the database yet nothing works.
