Question : Problem: Blackberries not receiving internal mail

I just upgraded my BES from 4.1.3 to 4.1.6 on a Windows 2000 box. I'm using Groupwise. My Blackberries will work with internal to external mail and vice versa, but it won't work with internal to internal. Any ideas?

Did you also apply the maintenance release after installing SP6?
