Hi,

I need to find all distribution groups that have more than 50 recipient. I tried with this in ems:

$grupe = Get-DistributionGroup
$grupe | Where-Object { (Get-DistributionGroupMember -Identity $_.Name).Count -gt 50 }

And it is working, but if I have group in group it only count 1 and not member in child group. Example:

Group01@test.com

• Group02@test.com

• Group03@test.com

• User01@test.com

• User02@test.com

For group01 number is 4, but i need total number of recipinet.

Use recursion - http://www.ericwoodford.com/node/290

This function is working, but only for one concrete group. I cannot pipe all groups.

function Get-DLMembersRecurse ($DL) {
         $memlist = @()
         $mems = Get-DistributionGroupMember $dl -ResultSize unlimited
         foreach ($m in $mems) {
                 if ($m.recipienttype -match "group") {          
                        Get-dlmembersRecurse $m.identity
                 } else {
                         if (($memlist -match $m).count -eq 0) {$memlist += $m           }
                 }       
        }
         return $memlist
 }

I use:

(Get-DLMembersRecurse group01).count 

Now need to count all groups on exchange.

$grupe | Where-Object { (Get-DLMembersRecurse $_.Name).count  -gt 50 }

Kazun, sorry for stupid question :) I tried this before last posting, but with error in typing and I have some error with identity. Thank you!

Pair was needing this information exported reports of distribution lists and found a very good script in this link: http://justaucguy.wordpress.com/2013/03/01/recursive-distribution-list-script/
