I tried setting up my employers email in Outlook 2011 for Mac.  Because this version is missing features that have been in Outlook for Windows for years, that just won't work, so I deleted that account.  I then set up another account, which works... but I still get errors that have to do with the old account.  How do I completely remove all references to the old, deleted account?  And why wasn't that done when I deleted the account from Outlook config?
