Mass update of distribution list members – Powershell

Some time ago I had to perform update of one of DLs with all mails from company.

I prepared a simple commands and will share it with you. The csv file is the export of emails I want to add. Imported file has 2 columns – surname and email address (primarySmtpAddress). 1st one column is not obligatory of course.

$userList = import-csv "C:\allMails.csv" -delimiter ';'


ForEach ($user in $userList) {

     Add-DistributionGroupMember -Identity "DL-TEST" -Member $user.PrimarySmtpAddress
         
}
