How to Sync Entra ID Users to Active Directory and Manage Them

According to a document I found, it seems like you can’t achieve this directly either. Creating the users on-prem and then linking them is the way to go. Here's the link to the Microsoft documentation: https://learn.microsoft.com/en-us/enctra/identity/hybrid/connect/how-to-connect-install-existing-tenant.

The feature you're looking for is called User Writeback. It used to be part of Entra Connect but got deprecated earlier. I’m not aware of it moving to Cloud Sync either. It seems like your AI is a bit off here! You should plan on carefully making this sync happen since converting existing cloud-only accounts into hybrid models isn’t just a simple task.

From what I've seen, the usual method involves creating accounts on-premises first and then syncing them, which means users would need to change their passwords. I haven't checked in about six months, though, so it's worth investigating if there have been updates since then.

Unfortunately, it's not possible to directly sync cloud-only accounts back into AD. You would need to create those users on-prem first. As long as the UPNs match, the cloud accounts can be linked correctly. But be aware the passwords will always update to whichever is newer, so users might still need to reset theirs.
