If the SQl server that hosts the BES database is offline for a few hours due to maintenance, will it affect the communication between the devices and the BES server? Will there be mail flow to the device?
It will work for 4 hours with no issues. Any longer than 4 hours and other transactions will begin to stack up. Although email will continue past 4 hours, it will be slow.
Like knottyrope says, don't reboot while SQL is offline, it's not pretty.....
If BES database is not available...?
