I hive found which user it are, but I cannot find what is which mailbox database attribute is wrong.
The MainMailbox is onpremise and Online Archive is in Office365. We get this message from several users different users onetime.
Can anyone confirm that this is standard behavior when the online archive mailbox is moved to office 365 and thus the notification only occurs once

- Hello Pascal,
This isn't standard behavior because Exchange should be aware of the archive mailbox being hosted in the cloud.
Did you already tried this to see if it was provisioned correctly?

So the migration has been good. But the event viewer mentioned for every mailbox that has been migrated this message.
So I think that when the handover take place, this message occur. I got this from every account that I migrated.
