I have been searching all the forums for the past few days and trying everything I can find to get this Blackberry Enterprise Server to work properly but have not had much luck. We originally had Blackberry Enterprise Server 4.1 on a Windows 2003 Server. We are removing that server from our inventory and needed to transfer the BB server. I tried using the installation disk for BES on the new server, a Windows 2008 64bit server but it would not run, I am assuming it was a 32 bit version. I went ahead and downloaded Blackberry Enterprise Server Express and was able to get it installed. I am able to add users and set an activation password which is correctly being emailed to the user, however when I try to use enterprise activation it never works. It will attempt and then retry and retry and then fail. When I first ran iemstest I was getting the "openmsgstore for this profile failed" error which I was able to get fixed but now I cannot get by the "No Send As" error. I have tried everything I can find on these forums to fix the problem and I cannot get it to work. Here is the printscreen of my iemstest.

Can anyone offer any help before I burn this Enterprise Server to the ground and buy my employees a non BB phone. Thanks in advance for any help.

The BESAdmin (or the BESXAdmin, how you named it) needs Send As rights. If you have given the Send As rights in Exchange, and it has lost it again, make sure that BESAdmin is not member of the Domain Admins group.

Details on how to give the correct rights via Power Shell:

Q. How do you set the BESadmin permissions in Exchange 2007?
