BES – Message Status: Desktop email program unable to submit message.
Windows 2003 SBS with Blackberry Professional Software Server installed in the SBS server.
I ran into this problem at a side job/contract job, that I worked last weekend. Although we don’t use SBS at the church, and this particular problem didn’t happen at the church, I wanted to post it on my blog for anyone doing a google search on the same problem. Hopefully you’ll find this blog sooner than later and save time troubleshooting.
You can install Blackberry Professional Software on Windows 2003 SBS. You’ll need to create your BESAdmin account in AD and be sure the account is a member of Domain Users (not admins). You’ll also need to make sure that BESAdmin has Send As rights on your Exchange Server. Then log into the SBS as BESAdmin. Once you have BES running correctly, you can log out and log back in as Administrator to mange your SBS server. If you need to do anything to BES, log back out and back in as BESAdmin.
Here’s the problem we ran into: the user could receive e-mail, and the calendar, contacts, etc seem to sync. But when the user tried to send an e-mail, he would get: Message Status: Desktop email program unable to submit message. We checked the users Security in AD and had to add the BESAdmin to the Security with Send As rights. Within 30 minutes later, the BESAdmin had disappeared from the Security on the account. Ultimately, our problem was that this particular user was part of the “domain power users” group. This is a privileged group. We removed the user from the group and all is well.
