Hello Everybody, users created in ADUC can have UPN different from User Logon Name (Pre windows 2000). It can be UPN: name.lastname@domain.com ULN: Lastname. In Hybrid environment, can this create any problems whatsoever, is there any best practice from Microsoft? Best Regards Gianluca

    Hi @Gianluca Giurato

    Of course you can without any problem. In hybrid environment it’s recommended to configure UPN suffixe with a routable domain . For more information please refer to the following article:
