Office 365: Off-boarding a mailbox

On-boarding a mailbox to Office 365 is a quite simple to do with the Exchange Management Console. But how to off board a mailbox. So you might ask why should I do that, well just to be prepared, just in case you have to.

First create a powershell session to O365:
$cred365= Get-Credential
$CloudSession = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell/ -Credential $cred365 -Authentication Basic -AllowRedirection -WarningAction SilentlyContinue
Import-PSSession $CloudSession -Prefix 365

Now run the move request:
New-365MoveRequest -Outbound -Identity 'user@domain.com' -RemoteHostName mail.domain.com -TargetDeliveryDomain domain.com -RemoteCredential $credOnP -RemoteTargetDatabase 'Mailbox Database 041637xxxx'


Afterwards you can find the new move request in EMC under your Office 365 tenant in "Move requests".
