MigrationRecipientNotFoundException

Question

I'm trying to set up a Hybrid Exchange 2013 migration. Exchange 2013 has been updated to CU12

I'm also using AADSync

User are created on the cloud and all replication on AADsync are success.

If i create a new user on PREM with mailbox, the user is replicated.

If i migrate this new user, the migration is SUCCESS (Good !)

But if i try to migrate an existant account, the migration failed with this message:

MigrationRecipientNotFoundException (no mail user)

On Exchange Online powershell the command Get-Recipient -Identity **** return the user correctly

Have you an idea ??

Hi Paracetamol,

About the MigrationRecipientNotFoundException error, does the entire error message look like the following?

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.

If yes, I'd like to explain that the root cause may be related to the Exchange Online server, and our relevant team is now working on a fix. Before the fix is completely deployed, it is recommended that you try this workaround:

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. If not, continue on.
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.)

And if the entire error message is not what I assume above, please provide it for further troubleshooting.

Thanks,

Allen
