Im on an iMac using OS X 10.8.5. I've been using Outlook for Mac 2011 for almost a year with no problems on a hosted Exchange server (Network Solutions). 

After a recent Microsoft update (14.3.9), Outlook crashed and had created a "recovered account."  Ever since then I can't access any accounts (Exchange or iMail) through Outlook Preferences (followed by Accounts) -- every time I try to do so the screen just freezes (I want to delete accounts that seem to have duplicated with the recovery). 

I'm receiving/sending emails through the accounts no problem -- but as noted I have duplicate accounts now (with thousands of emails) and can't delete the duplicate accounts (or do anything else with them for that matter). 

Any ideas?
