What the heck does this mean in English? Microsoft doesn't write crap like this without giving detail instructions how to properly configure something!! (sigh) I think RIM needs to have a lession or two in properly documenting stuff.

The service account requires a minimum of the following Microsoft Exchange 2003 permissions:
View Only Administrator. This permission should be set to enable (at minimum) access at the Administrative Groups level in Microsoft Exchange 2003 to be able to read from the Active Directory.
Administrator Information store, Send as, and Receive as. These permissions should be set at the Microsoft Exchange server level.
You must ensure your Group Policy does not conflict and override the permissions set for the BESAdmin
