FYI - BES gotcha We just went through a very similar change...BES 4 to BES 5, Exchange 2003 to Exchange 2003 to Exchange 2010 <and no, it's not a finger stutter!>. The only real issue we found was with the new MAPI profile for the BESADMIN account. It seems that it only accepts 20 connections, so 1/2 of our BES users didn't work. You need to use a PS command to change the default <unless I missed something>
And yes, 2 days with RIM tech support didn't help either... On Tue, Aug 3, 2010 at 3:19 PM, Maglinger, Paul <[email protected]> wrote: > Good information everybody.
