AD sync question
We have a customer that has activated a tenant with office 365 business licenses.
The tenant is not yet connected to AD .
On the tenant several users are already been created and assigned an office license
The users login are in the form z.user@company.onmicrosoft.com and used when the office application have been installed locally on the PC .
Now we're going to set up the AD Sync and wondered about the "duplication" of the users .
The AD users will be replicated with their UPN r.user@company.com but also with their tenant email address which will be the same as the one already present .
So what happen then to the users already registered in the tenant ?
Will they be impacted ?
thanks
Stefano

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
