    Hello, I am running into a few errors when running this command to 

    1. Get all distribution groups in AD.

    2. Count all distribution groups with 1000 members or less (recursively search for nested members)

    Get-ADGroup -Filter 'groupcategory -eq "distribution"' 

| Where-Object { ([array](Get-ADGroupMember –identity $_.distinguishedname -Recursive)).Count -lt 1000}

| Measure-Object

    Errors:

    Get-ADGroup -Filter 'groupcategory -eq "distribution"' 
| Where-Object { ([array](Get-ADGroupMember –identity $_.distinguishedname -Recursive)).Count -lt 1000} 
| Measure-Object

Get-ADGroupMember : An unspecified error has occurred

    Troubleshooting:

    - When I run the following I am able to get a count.

    (Get-ADGroup -Filter 'groupcategory -eq "distribution"').count

    - When I run a "like" filter the command works as well. 

    Get-ADGroup -Filter "name -like '*test*'" 

| Where-Object { ([array](Get-ADGroupMember –identity $_.distinguishedname)).Count -gt 3} 

| Measure-Object

    I am running this on Exchange Server 2016, Windows Server 2012 R2 Standard

    PS version 4.

    Get-ADGroup -Filter 'groupcategory -eq "distribution"' | 
    ForEach-Object{
        $group = Get-ADGroupMember –identity $_.distinguishedname -Recursive
        if($group.Count -lt 1000){
            Write-Host ('{0} = {1}' -f $group.Name,$group.count)
        }
    }

    Thanks! This provides me a count for each DL that is under 1000 members. For this solution, I will need to store the distinguished names of these DLs in a variable. What would be the best way to do that since Get-ADGroupMember only allows to specify a single DL?
