You can use the "soft match" process to "link" the AD user with an existing Azure AD one: https://support.microsoft.com/en-us/topic/how-to-use-smtp-matching-to-match-on-premises-user-accounts-to-office-365-user-accounts-for-directory-synchronization-75673b94-e1b8-8a9e-c413-ee5a2a1a6a78

VasilMichevReading the article I see that it works using the smtp address as soft match, it it requires that the users have an active mailbox on exchange online.

Unfortunately the customer has only on-prem exchange

thanks

It works on "mail" attribute as well, and if that is not an option, you can use UPN matching: https://docs.microsoft.com/en-us/troubleshoot/azure/active-directory/use-upn-matching-identity-sync

Or use the hard-match method: https://docs.microsoft.com/en-us/archive/blogs/praveenkumar/how-to-do-hard-match-in-dirsync
