Exchange 2010 powershell script enabling account services automatically

I used this script below to create exchange users from existing AD accounts. It does it well except for the fact that it enables OWA and pop3. Any reason why this automatically does this without me even specifying to do so. When I create an account by hand this does not happen.

$mailbox=import-csv C:\temp\mailusers.CSV
ForEach ($mailbox in $mailbox) {Enable-Mailbox -Identity $Mailbox.Identity -Database $Mailbox.Database | Enable-Mailbox –Archive -ArchiveDatabase $Mailbox.Database}
