Get-UserPrincipalNamesSuffix

 

Applies to: Exchange Server 2013

Topic Last Modified: 2014-03-05

This cmdlet is available only in on-premises Exchange Server 2013.

Use the Get-UserPrincipalNamesSuffix cmdlet to view the user principal name (UPN) suffixes in the Active Directory forest. The UPN suffixes are created in Active Directory Domains and Trusts.

Get-UserPrincipalNamesSuffix <COMMON PARAMETERS>
Get-UserPrincipalNamesSuffix [-Identity <ExtendedOrganizationalUnitIdParameter>] <COMMON PARAMETERS>
COMMON PARAMETERS: [-DomainController <Fqdn>] [-Organization <OrganizationIdParameter>] [-OrganizationalUnit <ExtendedOrganizationalUnitIdParameter>]

This example returns all UPN suffixes for the Active Directory forest.

Get-UserPrincipalNamesSuffix

UPN suffixes assigned to an organizational unit are stored in the upnSuffixes attribute in the Organizational Unit object.

The default UPN is contained in the Canonical Name attribute on the Partitions container object in the configuration naming context. The default UPN suffix identifies the domain in which the user account is contained. When you create a user account in Active Directory, the default UPN suffix is the DNS name of the first domain in your domain tree.

If you create user accounts by using Active Directory Users and Computers, every user must have a UPN.

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Recipient provisioning permissions" section in the Recipients Permissions topic.
