How to set Exchange UPN User Principal Names

Exchange allows you to use multiple domains for authentication. For example, for forms-based authentication or hosted exchange operation via virtual directories, user principal names (UPN) provide preferred logon security.

User Principal Name suffix is the name of the current domain and root domain, which are the default user principal name suffixes. Using alternate domain names increases login security and simplifies logins.

The Active Directory Domains and TrustsMMC console adds alternate user principal name suffixes.

The Exchange admin center enables forms-based authentication with User Principal Name (UPN) logon format under Server – Virtual Directories – owa (Default Web Site).
