Recently the brick level mailbox job has been failing. So I split the job into 2 (A-L) (M-Z) the old job takes 12hrs which is fine. the new job takes 6 hours each (same amount of time) My question is. Even though I start both jobs at the same time, only 1 runs at a time and the other starts right after. Is there any way of getting both brick level jobs to run at the same time or is this not possible?
