The method explained before is the only way to get email to contact.

Another manual method would be to say export your current contact list to a CSV. Using the formatted method you could add additional contacts to the .CSV from each emails. this method is really not recommend as it could produce duplicated entrees if the option is not selected.

Here is a site that has instructions Add Contacts for Outlook automatically.

Hope this helps.
