Exchange 2007 latest SP and RUHF
Half of users on XP - Outlook 2003 : These users have NO issues
Half of users on Win 7 - Outlook 2010 : These users have periodic white screen hanging of Outlook, seems to be when meeting requests or calendar related tasks are occuring.. though not sure
To date : Installed latest RU, tested performance of Exchange mail, CAS and HT servers .. no issues
Removed all add ins from outlook : still happening
Turned on logging in outlook .. nothing obvious
