AD sync question

[Stefano Colombo]

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-account...

@Vasil MichevReading 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
