Hello,
We have a strange issue with archiving tasks. We have 4 PRD Exchange servers and MBX archiving tasks for them. Scheduled tasks, Run Now and Sync of all mailboxes work properly only for the first one, but when it launches by Schedule or I do it manually for other 3 server- nothing happens, it means that I can't see event logs 3442\3448 that the task has started to work and finished, also no new running archiving reports and no Sync of mailboxes. We can see that previous task is working, as you can see on screenshot the task is working since yesterday, but nothing happens inside it, no progress since yesterday. Also, there is no any critical or error Event logs, it means that the task just hangs. Restarting of archiving tasks doesn't help, one time, setting backup mode and clearing backup mode helped to finish activing task without a progress, but the next scheduled task hanged again.
At the same time we can easily enable\disable users, check user archves from affected servers. The same issue was beetwen 16.12.2016 and 20.12.2016, the EV server was restarted and the issue has been fixed for 2-3 days. Could you clarify what is the best way to determine the root cause of the issue? Thx.
