Most companies use the built-in migration feature in the Office 365 Portal for onboarding mailboxes to the cloud. This has been recently upgraded with a lot of new features such as batches and migration end-points etc.
However a logical question is, what about migrating mailboxes back to our on-premises Exchange organisation? Creating those end-points can sometimes be difficult. To make life easier I use this simple PowerShell script. Before you can run the script you first have to connect to Remote PowerShell. For that please follow the instructions described here.
$opcred = get-credential domaindomainadminGet-Mailbox -Identity firstname.lastname@example.org | New-MoveRequest -OutBound -RemoteTargetDatabase ‘Database01′ -RemoteHostName ‘hybrid.contoso.com’ -RemoteCredential $opcred -TargetDeliveryDomain ‘contoso.com’
As you can see we define several parameters. Most of them should make sense to you, however I want to highlight that in a hybrid scenario you must use the database on your hybrid server. The RemoteHostName parameter is your hybrid endpoint.
