You will not need to - Outlook will ignore them anyway. You will get a
message saying some don't have an email address. So what.
If you want to see who doesn't have one, show the "email" field in the
Contacts Folder in any table styled View (eg By category). Turn on Advanced
Toolbar, click Field Chooser, drag the email field onto the view (drop it
beside the other fields ate the top of the table). You can sort by email -
just click that column header.
