I'm getting this message every few minutes. Seems to be related to when new emails arrive from our Exchange 2010 server.
I'm running Office 2011 for Mac. I'm on the latest update (14.3.2). I have rebuilt the Outlook database.

I saw one suggestion that proposed going in through Outlook Web Access and removing everything from the "Recovered Files". Did that.

Still getting this message every few minutes.

Anyone got any idea how to fix this?
