I'm running SBS2003 w/ Exchange 2003 Standard. We have 1 user with a Blackberry running on Blackberry Enterprise Server 4.1 and the flow of mail from the BES to the BB has always been instant. Recently, there is about a 10 to 15 minute delay between the Outlook Delivery and the BB delivery, and I cannot seem to figure out why. I'm not quite sure how to troubleshoot the problem to figure out if the delay is between Exchange and BES, BES and the carrier network, or anywhere inbetween. I did download the BES Resource Kit, but I'm not quite sure where to begin as far as what logging levels to enable in BES, what actual log files to analyze, etc... The only change that has been made to the server (The Exchange Server and the BES are on the same machine) is that we upgraded our version of Backup Exec to Symantec Backup Exec 12, which seemed to correlate to the same time frame that this delayed BES delivery began happening. The BES database is on a seperate machine on the network, and uses an MSDE 2000 instance. I've verified that the BES is communicating fine w/ the BES database as well as the SRP "network node" out on the Blackberry internet network.
