My company just installed 2008 SBS for a client (we're a SMB IT Consulting firm) and we're working on getting just a couple of BBs set up on the new server. We are using BIS (Sprint / Nextel) with 2007 Exchange. One user is getting mail but slowly. In addition, he is getting a message from RIM with each email that reads "This message is used to carry data between the BB handheld... Do not delete... It will be processed by the server". Is this message supposed to be deleted by the server and the BIS service automatically?
