Converting a Synced with Active Directory user to a InCloud user

Microsoft recently closed the loophole of deleting a AD user and restoring it in AzureAD/Office365 as a way of migrating user accounts to AzureAD.

Here is the currently supported method I was given by Microsoft Support and have successfully used.

Import-Module Azure 
$LiveCred = Get-Credential
Connect-MsolService -Credential $LiveCred

Set-MsolDirSyncEnabled –EnableDirSync $false
(I answered ‘y’ when prompted)

Wait until you stop getting the ADSynced user warning in the O365 portal when you try to edit a username, this takes around 10 minutes.

Set-MsolUser -UserPrincipalName test.user@example.com -ImmutableID ""

Wait 10 minutes.

Set-MsolDirSyncEnabled –EnableDirSync $true
(I answered ‘y’ when prompted)
This last step will take 6-8 hours-ish.

Once this is all finished and the sync re-starts you will see the user you cleared the ImmutableID for show as InCloud.
