Anyone done 2010 to 2016 migration with EV 12 with Both version running at the same time ?
After I've added 2016 to EV, moved EV service account to 2016, there are lots of erros.
1. Can't enable mailbox created on 2016 - freezes and timesout.
2. Lots of Event ID 3230
Could not create a new MAPI session on Exchange server 'Server1.
The most likely cause is a connection issue that is causing excessive delays in the task. This can often be recovered by restarting the MAPI related tasks.
Unable to get exclusive access to the MAPI thread pool.
Mutex name: Lie mode lock
Reason: Last lock holder: Process <17176> <ArchiveTask> Thread <11164>
3.Lots of Event ID 7206
A locking error has occurred in CEVMAPILieModeLock : 0x102
Internal reference: STRL Write Mutex HrMAPIOpenMsgStoreKvs

* before adding 2016 server with support, everhyting is working fine.
So far, support is just pulling articles and have not been able to move forward for couple of days.
Sounds similar to another issue posted here. So I would suggest the same thing.
You can check if the throttling policy is set from exchange 2016 server:
