Remove SMTP from AD attribute

Hello all,

I need to remove some SMTP addresses for a domain that will be going away. My plan is to round up the users who are no longer receiving at the address, and put there usernames in a csv file. Then run the below at the end of the day. Am I going about this the right way?

$users = names.csv foreach($user in $users){ Set-ADUser -Identity $users -Remove {$_.proxyAddresses -eq "*@domain.com"} }
