Hi all,
We are migrating to O365. Exchange 2010 Hybrid environment is deployed.
Randomly, we get some errors when migrating Mailbox to Exchange Online, like StalledDueToTarget_DiskLatency or StalledDueToTarget_Processor. If we remove the move request and create a new one, the Mailbox is migrated.
These esrrors are from Exchange On-Prem side or O365 servers side?
Thanks

Hi Thomas,
The errors are mostly like to be related to the unhealthy on-premises server or the source mailbox (on-premise mailbox) contains some special item(s). Since creating a new move reques works well, my understanding is that the on-premises server should be good. For more information, you can refer to https://support.microsoft.com/en-sg/help/3162761/-stalledduetotarget-processor-error-during-exchange-migration-in-offic.
