Delete multiple members of distribution group using CSV thru Exchange Management Shell On Premise

Gatchalian, AD 25

I received a request from our employees to delete all the members of this particular distribution group within our organization, and upon checking this DL has a total of 7,000 members.

Is there any powershell script I can use to delete just the members of this DL?

Thank you,

You may try the following PS script

$memberlist = Get-DistributionGroupMember -Identity <dl name> $memberlist | % {Remove-DistributionGroupMember -Identity <dl name> -Member $_.Name -Confirm:$false}

I think that's going to remove ALL members from the DL, not just the users in the AD forest.

Try this:

$DLName = "MyDL"
Get-DistributionGroupMember -Identity $DLName> -Resultsize Unlimited |
    ForEach-Object{
        Try{
            Get-ADUser $_.Identity -ErrorAction Stop    # if there's no AD user don't try to remove it
            $_ | Remove-DistributionGroupMember -Identity $DLName -Member $_.Identity -Confirm:$false
        }
        Catch{
            # log some information?
        }
    }

NOTE: I haven't tried running this code!!!!!
