How do I stop Outlook from rendering an email address as a mailto: link?

Question

I am creating an HTML email to be sent to a user. If there is a valid email address to within an HTML email, Outlook will render it (normally helpfully) as a mailto: link.

Answer 1

type the first few letters of the email address you want to get rid off like you are preparing to send an email to it. Outlook immediately proposes you a list of persons for which the address is similar. Click on the cross next to the adress that you want to delete, et voila. This is for Outlook 2010.
