Hi guys, i have recovered an On-Prem DC from backup that had AAD sync, however users who were created in the last 6 month are missing, but they do appear on the Azure AD. I have re-created the last 6 months users on the On-Prem AD, now i want to sync them to Azure without them losing their old mailboxes, how to i go about it?
