I have an odd problem that is driving me nuts. There are about a dozen users out of 500 that can't send initially. And by initially, I mean that when they compose a new message, it won't send but if they try to resend, it will eventually go through. It may take 3 or 4 resends but it goes through. There is nothing special about these accounts that I'm aware of. They receive mail fine and other than two exceptions, their calendar syncs fine as well. Restarting the dispatcher service or even rebooting the server may give temporary relief but if it does, it's broken again within a few hours. I should also mention that pin to pin messages work during this time.
I can't see anything in the logs that show an error. Event logs are clean as well. I didn't scour everything but nothing struck out as a problem. The specific error that shows up on the device is:

I'm running BES 4.1.4 MR4 for Exchange with Exchange 2007. The BES is running on adequate hardware with more resources than it needs. It has 2 teamed gig NICs so the connection to Exchange is plenty fast. The BES is behind a somewhat flacky firewall but if that were an issue, I imagine it would affect all users. Exchange is not behind that firewall. It's also not a problem with the cell network since affected users are on different networks. Any ideas???
Thanks!
