Mail migration IMAP to Office 365 fails when run for a 2nd time
Hi,
for some mailboxes a migration from IMAP mailboxes to O365 has been started in the past. It run successfully for some time.
After a while it was stopped and the connection was closed. The old migration requests were deleted from Exchange admin console.
Now a new try to start the migration fails with error
UserAlreadyBeingMigratedException: The user 'USERNAME@domain.dom' already has a pending request.
Please remove the existing request and resume the current batch or start a new batch for this user. --> Name must be unique per owning mailbox.
There's already a request with the name 'IMAP:user@domain.de' owned by mailbox 'EURPR01A008.PROD.OUTLOOK.COM/Microsoft Exchange Hosted Organizations/NAME.onmicrosoft.com/USER'.
The following commands don't report anything
get-migrationuser
Get-MoveRequest | fl
How can the mailbox migration be restarted or the existing requests being removed?
Hello magriii405,
Did you check if there is SyncRequest in place?
Get-SyncRequest -Mailbox <Affected User SMTP>Please refer to this article for more information.
Hope that helps.

iHi AndySvints,
there was a SyncRequest running. It's strange that this request is still not visible in the Exchange Admin Web page (neither old nor new interface). I wonder why I didn't come across the article you mentioned.
Thank you very much for your help.
