MigrationRecipientNotFoundException with existing Mail User

I'm am trying to migrate users from an on premises exchange 2013 server to office 365 all but one of the mailboxes have moved successfully.

Error: MigrationRecipientNotFoundException: A recipient wasn't found for "*** Email address is removed for privacy ***" on the target. Create a recipient of the appropriate type for this migration on the target and try again.

I have checked that the user has synced with azure ad and exists in contacts and with get-MailUser in powershell on exchange online and tried creating a new user and moving the new user to office 365 works. I have also tried removing the user from office 365 including deleted users and allowing to resync.

Thanks

Oli

    Hi Oli,

    Regarding the error “A recipient wasn‎'t found for "*** Email address is removed for privacy ***" on the target. Create a recipient of the appropriate type for this migration on the target and try again”, I would like to share a workaround first:

    1. Run Get-Mailbox -SoftDeletedMailbox to list the deleted mailbox users. If the affected users are included, run Remove-Mailbox -PermanentlyDelete to completely remove them.
    2. Run Get-MailUser -Identity <user> | FL GUID to get the GUID of the user.
    3. Run New-MoveRequest -Identity <GUID> -Remote -RemoteHostName 'mail.domain.com' -RemoteCredential $cred -TargetDeliveryDomain 'domain.mail.onmicrosoft.com' -BadItemLimit 10 -LargeItemLimit 20 to try a new batch to move the mailbox.

    Note: please replace all the domain names included in the commands above.

    If this cannot work either, please choose an affected user and run Get-Recipient -Identity "*** Email address is removed for privacy ***" | FL from both Exchange Online and Exchange on-premises. I have sent you a private message to collect the PowerShell results. You can see it and reply to me via: https://community.office365.com/user/conversations

    Regards,

    Poppy
