Get Exchange Distribution List Members using Powershell

We can get and list Distribution group members using the Exchange Powershell cmdlet Get-DistributionGroupMember. In this article, I am going to write Powershell script to get distribution list members, export distribution list members to CSV file and export distribution groups and members to CSV file.

Get Distribution List members

Run the following command to enable Exchange cmdlets if you are working with normal PowerShell console instead of Exchange Management Shell.

Add-PSSnapin *Exchange*

Use the following Powershell command to list Distribution group members.

Get-DistributionGroupMember -Identity <Group-Name>

By default this command returns only two properties (Name and RecipientType) of the Group members. You can select required values by using select command.

Get-DistributionGroupMember -Identity <Group-Name> | Select Name, RecipientType, PrimarySMTPAddress

Export Distribution List Members to CSV

The following Powershell script gets a list of distribution group members and exports output to CSV file. Replace the distribution group name “TestDG” with your own group name in the below script.

$DGName = "TestDG"
Get-DistributionGroupMember -Identity $DGName | Select Name, PrimarySMTPAddress |
Export-CSV "C:\Distribution-List-Members.csv" -NoTypeInformation -Encoding UTF8

Export Distribution Groups and Members to CSV

The following PowerShell script gets a list of Distribution groups and its members and exports output to CSV file.

$Groups = Get-DistributionGroup
$Groups | ForEach-Object {
$group = $_.Name
$members = ''
Get-DistributionGroupMember $group | ForEach-Object {
        If($members) {
              $members=$members + ";" + $_.Name
           } Else {
              $members=$_.Name
           }
  }
New-Object -TypeName PSObject -Property @{
      GroupName = $group
      Members = $members
     }
} | Export-CSV "C:\Distribution-Group-Members.csv" -NoTypeInformation -Encoding UTF8
