Good morning everyone.
Environment.
Microsoft Exchange Server 2007 SP1
BES Server Version 4.1.6.20
This environment works correctly, BES currently has 100 users.

By necessity BES Express install 5.03, but without success.
Install different versions of operating systems.
Windows 2008 R2 64B
Windows 2003 32B
I did a review of BSAMIN user permissions to use the service generated, apparently all right.
ImTEsts.exe utility produces the following result.
