Re-sync AD Account with Azure AD account after deletion, restore or migration

Issues may occur when accounts have been created incorrectly or have been deleted and restored

You may need to manually re-sync the AD objects between on prem AD and Azure AD

This is done using the ImmutableID.

First get the account in Active Directory and get the immutable ID then convert it to Base64 String:

• Get-ADUser -Filter "name -eq '<username>'" -Properties objectGUID | Select-Object UserPrincipalName, objectGUID, @{Name = ‘ImmutableID’; Expression = { [system.convert]::ToBase64String(([GUID]$_.objectGUID).ToByteArray()) } } | Export-CSV users.csv

Then set the Immutable ID obtained from the AD account on the Azure account:

• Set-MsolUser -UserPrincipalName USER@DOMAIN.COM -ImmutableID “ABCdefGHIjklMNO==”
