MigrationPermanentException: Cannot find a recipient that has mailbox GUID

Помилка: MigrationPermanentException: Cannot find a recipient that has mailbox GUID.

When trying to move a mailbox from Exchange Online to Exchange On-premises the above error occurred.

Error: MigrationPermanentException: Cannot find a recipient that has mailbox GUID

This happened because the mailbox was created online and not on-premises, and therefore the GUID wasn’t synced to AzureAD and vice versa.

In Exchange Online PowerShell:

1. Connect to Exchange Online with Windows PowerShell:

$MSCred = Get-Credential

$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell -Credential $MSCred -Authentication Basic -AllowRedirection

Import-PSSession $Session

2. Run the next command

Get-Mailbox alias | FL ExchangeGUID

3. In the On-Premises Exchange PowerShell:

Set-RemoteMailbox Alias -ExchangeGUID 12345678-1234-1234-12345678

ПРИМІТКА: Use GUID from the step “2” above.

Wait for replication to AzureAD or force replication manually. Your mailbox should move to without a hitch.
