We upgraded from BES Express 4.1.6 to Bes Express 5.0.1 (by upgrade, I mean, uninstall 4, and install 5, and setup all users fresh, as I didn't want to bother with trying to migrate if that was even possible with only 5 users).

Since the change to 5.0.1 we have been getting errors in the server Application logs.

Our platform is MS SBS 2003 SP2 with all available Critical and recommended updates installed.

I have installed BES Express 5.0.1 on SBS 2008 servers without a hitch and no errors logged. The difference is obviously the platform, and also the fact that they were not changed from 4 to 5. I'm not sure if it is a comination of the two or what it is. I have tried Googling it, but the results I came up with were very few and without resolution.

Any help would be appreciated. At this time, everything seems to be functioning correctly, and all the users are able to sync fully, so it is not a mission critical thing. Just one of those situations where it would be nice to know the cause and to be able to clear up the Event Logs.

thank you
