Hello All,

Hope this post finds you in good health and spirit.

This post is regarding userPrincipalName [UPN] and hoh we can add additional UPN in domain.

The user’s login name is included in the userPrincipalName attribute. The user principal name (UPN), which is the most typical login name for Windows users, makes up the characteristic. Typically, users connect on to a domain using their UPN. This attribute is a single-valued, indexed string.

What is UPN

A UPN is a user’s Internet-style login name based on the RFC 822 Internet standard. The UPN is simpler to recall and shorter than a well-known name. This ought to correspond to the user’s email address. The purpose of the UPN is to combine the email and login namespaces into a single name that the user only has to remember.

What console will you use to configure additional upn suffixes for your domain?

Via Active Directory Domain and Truest Console, we add more UPN. Additionally, numerous UPNs can be added and configured at the OU level.

Below are the steps to add the UPN in domain.

• Right-click Active Directory Domains and Trusts in the left pane
• Select Properties from the menu.
• In the dialog box on the UPN Suffixes tab
• Type the name of the suffix that you would like to add to your AD forest in the Alternate UPN suffixes box.

Close the Active Directory Domains and Trusts console and one the active directory user and computer console and create the new user , you will see the new UPN as per below screenshot.

So, that’s all in this blog. I will meet you soon with next stuff .Have a nice day !!!
