Can't use the Exchange admin center to remove members from a distribution group

Original KB number:   3031293

Symptoms

When you use the Exchange admin center (EAC) to delete a member from a distribution group, you can't find the member in the list.

Cause

The cause of the issue varies depending on whether you're using on-premises EAC or the EAC in Exchange Online.0

  • In the EAC in Exchange Online, only a maximum of 1,000 members are displayed. If the distribution group contains more than 1,000 members, some members won't appear in the displayed list.
  • In on-premises EAC, only a maximum of 3,000 members are displayed. If the distribution group contains more than 3,000 members, then not all members are displayed. In this scenario, you can't use the on-premises EAC to remove members who aren't displayed.

Workaround

Use the workaround that's appropriate for your scenario.

EAC in Exchange Online:

If the member you want to remove isn't in the displayed list of 1,000 members, you can search for the member and then remove them.

On-premises EAC:

Use the Remove-DistributionGroupMember cmdlet to remove members from a distribution group instead of the on-premises EAC.

For example, to remove roger@contoso.com from a distribution group that's named Customer Service, follow these steps:

  1. Use one of the following options:

  2. Run the following command:

    Remove-DistributionGroupMember -Identity "Customer Service" -Member roger@contoso.com
