How to get all emails from ActiveDirectory using PowerShell without using Get-AdGroupMember?

I'm trying to download all emails from AD groups using PowerShell. The following recursive command works for most groups except any with more than 5000 members (including sub-groups).

Get-AdGroupMember "groupname" -recursive | Get-AdUser -properties Emailaddress | Select EmailAddress | Export-Csv c:\list.csv

Open in new window


The following error occurs with the recursive command returning more than 5000 members:

Get-ADGroupMember : The size limit for this request was exceeded.

The issue I have is my IT department will not increase the max member allowed to be queried (5000) on the AD web server.

A quick web search will yield the following solution but it is not recursive, and I need it to be recursive to get the emails from the sub groups (as we have many sub-groups).

$grp = get-adgroup "groupname" -properties members 
$grp.members | get-aduser | Select Name | Export-csv C:list.csv

Open in new window


Is there any other way to download all emails?

Try..
Function Get-GrpMember ($Group){
Get-ADGroup $Group -Properties Members | 
 Select-Object -ExpandProperty Members | 
  Get-ADObject -properties Samaccountname | %{
	If ($_.ObjectClass -eq "user"){
	 $_ | Get-aduser -Properties * | ?{$_.EmailAddress} | Select EmailAddress
	}ElseIf($_.ObjectClass -eq "group"){
	 Get-GrpMember $_
	}
  }
}
Get-GrpMember "groupname" | Export-Csv c:\list.csv -nti

Subsun, worked great! Minor issue: it does return duplicates (from sub-groups, not a big deal). Is there anyway to prevent duplicates initially so it doesn't have to be done post-processing?

change last line to..
Get-GrpMember "groupname" | Select * -Unique | Export-Csv c:\list.csv -nti

Open in new window

Or
Function Get-GrpMember ($Group){
Get-ADGroup $Group -Properties Members | 
 Select-Object -ExpandProperty Members | 
  Get-ADObject -properties Samaccountname | %{
	If ($_.ObjectClass -eq "user"){
	 $_ | Get-aduser -Properties * | ?{$_.EmailAddress} | Select EmailAddress
	}ElseIf($_.ObjectClass -eq "group"){
	 Get-GrpMember $_
	}
  } | Select * -Unique
}
Get-GrpMember "groupname" | Export-Csv c:\list.csv -nti

Open in new window
