We are running Exchange 2007 SP2. I have been asked by Management to find out what DL's a list of about 20 DL's are members of. I can view this by going to the DL's in question in Exchange Management Console > Properties > Member Of But was hoping there would be a way in Exchange Management Shell to do this? I can't seem to find one though.

You could do something like this but it might take a long time if you have loads of DLs with loads of users... ForEach ($DL in Get-DistributionGroup) { Get-DistributionGroupMember $DL -ResultSize Unlimited | % { If ($_ -match "distribution_list") {$DL.DisplayName} }} Just replace "distribution_list" with the display name of the DL you want to check. http://LetsExchange.blogspot.com

If for every DL you want to list all members that are DLs, you can run the following: ForEach ($DL in Get-DistributionGroup) { Write-Host "`n$($DL.DisplayName)" -ForegroundColor Green Get-DistributionGroupMember $DL -ResultSize Unlimited | Sort Name | % { If ($_.RecipientType -eq "MailUniversalDistributionGroup" -or $_.RecipientType -eq "DynamicDistributionGroup") { Write-Host "`t$($_.DisplayName)" } } } Hope this helps! http://LetsExchange.blogspot.com

But what about indirect membership? Or membership in groups that aren't mail-enabled? --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

I might be wrong, but I don't think he's looking for those scenarios. Sheen, can you confirm if this is what you want? You might want to add: -or $_.RecipientType -eq "MailUniversalSecurityGroup" http://LetsExchange.blogspot.com

If you're running that from Exchange 2010, you'll have to slightly change the first line because of the pipeline (really don't like how the pipeline works in 2010 compared to 2007...): ForEach ($group in get-distributiongroup) { $dn = (get-group $group).distinguishedname $g = [ADSI]"LDAP://$dn" $mo = $g.memberof if ($mo.count -gt 0) { write-host "DL`: $($_.name) is a member of`:" foreach ($m in $mo) { write-host "`t$((get-group $m).name)" } } } Otherwise you will get the following error: Pipeline not executed because a pipeline is already executing. Pipelines cannot be executed concurrently. + CategoryInfo : OperationStopped: (Microsoft.Power...tHelperRunspace:ExecutionCmdletHelperRunspace) [], PSInvalidOperationException + FullyQualifiedErrorId : RemotePipelineExecutionFailed But since he's on 2007, it is fine. It works great, thanks for the tip!! :) Sheen, all you have to do is exclude "normal" security groups if you just want DLs.http://LetsExchange.blogspot.com
