Mailbox switch tasks do not complete. Migration on same mailbox completes successfully.
说明
Mailbox switch tasks do not complete. However the earlier migration on same mailbox for which the switch had been performed completed successfully. In the On Demand core 'Tenants' page we have granted all the Migration consents for the migration account on the Source tenant and the migration account for the Target tenant.
There's no errors / details what is going wrong in the event log for the Switch task. Just one event--that the task has started. And then the task just hangs.
原因
There is another place in On Demand Migration (ODM) where the migration accounts are specified and consents granted. Under 'Configure Connection'. It may be that those accounts are consistent with what is configured in the 'Tenants' screen. Or that the consents granted have expired here.
解决办法
Ensure that in both dashboard areas (general 'Tenants' page of On Demand tool and the 'Configure Account' page of the On Demand Migration tool) being used for the migration account of the source tenant and the target tenant are consistent with each other. And that both have been granted the consents.
其他信息
migrate is read source and write target
switch is R/W and R/W
So the switch actually needs more permissions than the migrate.
