How to add UPN Suffix

Sometimes when you install Exchange, you want to allow users to use their e-mail addresses as a login name. Most of the time UPN suffixes are not usefull. For example you have internal name for domain “company.corp”, but your e-mail addresses are “username@company.com“. You want to give an option for users to log into OWA using “username@company.com” instead of “company.corp\username”.

To be able to use this, you need to define additional UPN suffix at domain level by following these steps:

  • Open Active Directory Domains and Trusts
  • Right-click on Active Directory Domains and Trusts
  • Choose Properties
  • Enter additional UPN suffix
  • Change UPN suffix for a client in Active Directory
