Exchange Unavailable each morning

I have a SBS 2003 Server fully up to date on patches.  This server has Symantec AV Corporate edition 10.2 and Symantec Mail Security for Exchange v 6.x

For the last several months and everyday this week, when the users arrive in the morning their e-mail is not working.  They cannot open Outlook as the information store is not available.  The server does not show any service as stopped but if we try to restart the information store it hangs.  Any service we try to restart (including the SMSMSE service) it hangs.  We end up having to restart the server to get things flowing again.

Any thoughts as to this issue?  I have another server same setup with the same issue but not as frequent.

Thanks
Paul

Watch Question

What is the size of the database ?

See the app log and check whats the error you get every morning there?
Try and narrow down the time at which this happens overnight this will be the key to solving this, it could be to do with the Anti-Virus file protection scanning the exchange MDBDATA folder but that wouldn't explain the other services acting up. You could disable the desktop/file  protection on the server for a couple of days to rule it out. You can write a couple of batch files to start/stop services and schedule them after hours e.g information store. I know stopping the information store overnight might cause a couple of bounce backs but it's worth it to get to bottom of this. I'd be interested in the app/system logs , you may have to up the logging levels in exchange.

I got a message about the virus definitions on the smsmse being corrupt or not available.  I've run live update successfully.  There are some other app logs for exchange.  I've attached a zip with several txt files of the event logs.

Thanks for your help

The size of the exchange database and log files are both under 4 GB
From the event IDs...it looks like your backup is schedule at 4 AM onwards and also SQL is doing some sort backup/restore....now Exchange Database also has online maintanence schedule at 5 AM (default)...this might be causing some issue. Please make sure two activities are not clashing with eachother...this might help.
XCHIExpert is right, you've got backup issues. I would be tempted to disable or reschedule backups for 1 night and see if your mail store is working in the morning. Work backwards from there, check the scheduled tasks for volume shadow copying, you could temporarily disable this too.
