Hi,@Nana Poku

Thanks for posting your question in the Microsoft Q&A forum.

According to your description, the on-premises AD can be synchronized to Entra, which means the on-premises AD connector is intact, but there is a problem synchronizing Entra to Exchange Online.

The forums can't solve the backend problem at the moment.It is recommended that you open an SR at the M365 center.
