Use the Remove-DynamicDistributionGroup cmdlet to delete an existing dynamic distribution group. This cmdlet removes the dynamic distribution group from Active Directory.

Remove-DynamicDistributionGroup -Identity <DynamicGroupIdParameter> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-IgnoreDefaultScope <SwitchParameter>] [-WhatIf [<SwitchParameter>]]

Parameter Required Type Description




The Identity parameter specifies the dynamic distribution group that you want to remove. You can use any of the following values for the dynamic distribution group:

  • Distinguished name (DN)
  • Canonical name
  • GUID
  • Name
  • Display name
  • Alias
  • Legacy Exchange DN
  • Primary SMTP e-mail address




The Confirm switch causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm switch.




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




The IgnoreDefaultScope parameter instructs the command to ignore the default recipient scope setting for the Exchange Management Shell session and use the entire forest as the scope. This allows the command to access Active Directory objects that aren't currently in the default scope. Using the IgnoreDefaultScope parameter introduces the following restrictions:

  • You can't use the DomainController parameter. The command uses an appropriate global catalog server automatically.
  • You can only use the DN for the Identity parameter. Other forms of identification, such as alias or GUID, aren't accepted.




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.

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 "Dynamic distribution groups" entry in the Mailbox Permissions topic.
