I know it's not in the compatibility matrix, too new. But has anyone had problems with their BES working with a server that's been upgraded to 2010 SP3? It's currently on SP2.
Re: Any issues with Exchange 2010 SP3 on 5.0.4 MR2?
We're going to go with SP2 rolliup 6 which includes the retention option we need. Since it specifically includes a fix for Blackberry, we figure it's fairly safe to load.
