PS Scripting Errors

Good Afternoon,

I'm trying to run script you provided about 4 years agao

$DGs=Get-DistributionGroup|where{(Get-DistributionGroupMember $_|foreach{$_.PrimarySmtpAddress})-contains "user@domain.com"}
 
foreach( $dg in $DGs){
Remove-DistributionGroupMember $dg-Member user@domain.com
}

But I get an error when I try to run. I do understand that there is programming script error but I don't know how to fix it.

I'm trying to remove a user from multiple distribution lists by using your script. My environment does not have AD integration at this time.

I get the error msg below when I try to run your script.

Cannot process argument transformation on parameter 'Identity'. Cannot convert

Any help would be greatly appreciated
