Just installed Mountain Lion. When I startup Outlook (Office 2011 for Mac), it connects to the server but it drops connection to Exchange Server after  few seconds to minutes. Keeps asking me to reenter my userid and pw.  After a couple of these events, my account is then locked on the server.  I have rebuilt the database twice, Shut down computer, reset the Parameter Ram.  An interesting issue is that I am running Parallels on my computer and Outlook on the PC side works perfectly. I am frustrated and about to reinstall OS10.6.8.  Any help out there would be appreciated
