Use the Enable-DistributionGroup cmdlet to mail-enable an existing universal group.

enable-DistributionGroup -Identity <GroupIdParameter> [-Alias <String>] [-Confirm [<SwitchParameter>]] [-DisplayName <String>] [-DomainController <Fqdn>] [-PrimarySmtpAddress <SmtpAddress>] [-WhatIf [<SwitchParameter>]]

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 "Distribution groups" entry in the Mailbox Permissions topic.


Parameter Required Type Description




The Identity parameter specifies the identity of the distribution group.

This parameter accepts the following values:

  • Alias

    Example: JPhillips

  • Canonical DN

    Example: Atlanta.Corp.Contoso.Com/Users/JPhillips

  • Display Name

    Example: Jeff Phillips

  • Distinguished Name (DN)

    Example: CN=JPhillips,CN=Users,DC=Atlanta,DC=Corp,DC=contoso,DC=com

  • Domain\Account

    Example: Atlanta\JPhillips

  • GUID

    Example: fb456636-fe7d-4d58-9d15-5af57d0354c2

  • Immutable ID

    Example: fb456636-fe7d-4d58-9d15-5af57d0354c2@contoso.com

  • Legacy Exchange DN

    Example: /o=Contoso/ou=AdministrativeGroup/cn=Recipients/cn=JPhillips

  • SMTP Address

    Example: Jeff.Phillips@contoso.com

  • User Principal Name

    Example: JPhillips@contoso.com




The Alias parameter specifies the e-mail alias of the group.




The Confirm switch can be used to suppress the confirmation prompt that appears by default when this cmdlet is run. To suppress the confirmation prompt, use the syntax -Confirm:$False. You must include a colon ( : ) in the syntax.




The DisplayName parameter specifies the display name of the distribution group. A display name is typically the same as the Domain\Account Name.




The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory.




The PrimarySmtpAddress parameter specifies the primary SMTP address for the distribution group. By default, the primary SMTP address is generated based on the default e-mail address policy. If you specify a primary SMTP address by using this parameter, the cmdlet sets the EmailAddressPolicyEnabled attribute of the distribution group to $false, and the e-mail addresses of this distribution group won't be automatically updated based on e-mail address policies.




The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf switch.

To see the input types that this cmdlet accepts, see Cmdlet Input and Output Types. If the Input Type field for a cmdlet is blank, the cmdlet doesn’t accept input data.

To see the return types, which are also known as output types, that this cmdlet accepts, see Cmdlet Input and Output Types. If the Output Type field is blank, the cmdlet doesn’t return data.

This example enables the distribution group Distribution Group1.

Enable-DistributionGroup -Identity "Distribution Group1"
