I'm sure my searching is just failing me...
I am transitioning to Exchange 2010 from Exchange 2007. It will take me 30 days or so to move all of my mail users. During that time I need to have Blackberry users on both 2007 and 2010.
I have a single user on Exchange 2010 - just a standard "Domain User" test account. I am unable to activate a Blackberry for the test user.
The EPT file just sits in their mailbox.
MAPI/CDO version is consistent across all servers. All users on Exchange 2007 are working fine.
The question I have is - do I have to move my "BESAdmin" to Exchange 2010 before I move any other users? Or is there some additional permission that is required for them to access my 2010 users?
I prefer not to move BESAdmin right away if possible, since it will cause downtime and if it doesn't work right away my boss and end-users get grumpy....
