Count number of users in distribution group

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.
