  All of them are @domain.com so all are the primary domain.  One is the primary address.

  Addresses are automatically applied to mailboxes according to your e-mail address policy.  Configure e-mail address policy so that it is being applied to mailboxes the way you want.  You can then apply the e-mail address policy as changed to all mailboxes, but be warned that this is dangerous and may make changes you don't expect.  It's safer to remove addresses manually, but it's generally more time consuming, of course.

  You can follow this to remove that:

  Use one txt file that contain all the users which you want to remove all the smtp addresses except primary smtp address.

  Then run this script to help you remove:

  $mailboxes=Get-content "C:\username.txt"| get-mailbox

  $mailboxes| foreach{

  $Emailaddresses=$_.Emailaddresses

  for($i=0; $i -lt $Emailaddresses.count; $i++){

  $Emailaddress=$Emailaddresses[$i]

  if($Emailaddress.IsPrimaryAddress -eq $true){

  $Emailaddresses=$Emailaddress
  }

  }

  set-mailbox $_ -Emailaddresses $Emailaddresses

  }

  Thanks,

  Evan
