Azure AD UPN Suffix RRS feed

  • Question

  • Hi,

    i am currently developing an interface to Office 365 and Azure.
    Currently i need to know how to indentify the domain of a user.
    I get the objectid and the UPN Name.
    Is there a direct association between the UPN Name and the domain name?
    In Active Directory I can set more then one UPN Suffix, which can be used.
    Can I set even more than one UPN Suffix in Azure for one Domain or can I use the suffix as a direct association?

    Thank you.

  • "domain" has a different meaning in Azure AD, what you probably need is the "tenant domain", aka the tenant.onmicrosoft.com value. But no, there are no UPN suffixes in Azure AD and the "domain part" of the UPN is the actual "domain".

  • Hi,

    while there is no real thing like UPN suffixe in Azure AD you can register multiple dns domain names in one Azure AD tenant. Each of them you can use also for the UPN of Azure AD users.

    So is feels a bit like the onPrem UPN Suffixes.
