Keith -
If you want, zip up a day of log files from a day they did maintenance and I'll point out some entries to you that would indicate a MAPI problem (email it to
hdawg@port3101.org).
That said, if you're going to do an early morning review of log files ... why not just restart the BES and deal with the 2 minutes of downtime instead of spending the time looking at the logs.
I understand the desire to understand what is going on and to justify a reboot (and to not reboot if not needed) but from a process perspective I think you may end up putting in more effort than needed here.
