Hi,

You can export all distribution groups and their members to a .csv file for backup, using the cmdlet below.

$groupmembers = foreach ($group in Get-DistributionGroup) { get-distributiongroupmember $group | select Name,@{n='DistributionGroupName';e={$group.Name}} }
$groupmembers | Export-Csv C:\DGgroupmembers.csv NoTypeInformation

For your reference:

Hope this can be helpful to you.

Best regards,

Ok This works well however the code do not displays DLs with no members (empty DLs) .Please suggest.
