I recently went  through a massive delete of all deleted e-mails in my Outlook for Mac 2011 (15,000+)  Now Outlook won't download any new messages.  The "Updating Message List" indicator in the lower right is frozen, but it does seem to keep track of the number of messages to download; i.e. the denominator "0/178" etc grows as time goes by.  Has anyone else seen then and how did you solve it?
