Hi @Glenn Maxwell

Agree with the suggestions above from AshokM, we can use the Update-DistributionGroupMember to meet this requirement

Here is also a related thread discussed about this similar question as yours: Add multiple members to distribution group with one call?

$NewMembers = Get-Content <path to member list text file>  
$CurrentMembers = (Get-DistributionGroupMember -Identity GroupName).PrimarySmtpAddress | where {$_ -ne ""}  
$NewMemberList = $CurrentMembers + $NewMembers  
Update-DistributionGroupMember -Identity GroupName -Members $NewMemberList -Confirm:$false

Hi,

This command looks good and it should work. Could you please let us know what exactly happens when you initiate this command for 10000 users. Any error messages?

Also, are you able to get that 10000 names when you run Import-CSV C:\list.csv?

You can also try using Update-DistributionGroupMember, but this will replace the current members of the DL. So, get the current members using Get-DistributionGroupMember and update the membership using the same CSV.
