Configuring preferences and options in Outlook.com
I too submitted a ticket to Outlook Help with the text "Please disable Safe Links for the following email aliases;(Your email address here..)
I received a response with similar text as above but which included the quote below stating that if I reply to their reply, I can "have the feature deactivated on your behalf". I just replied in the affirmative to that email. We will see what comes of it.
(Quote from supports response...)
*"*To provide the best protection for your account, these features are on by default and not designed to be turned off. You can reply to this email to have the feature deactivated on your behalf, but we do not recommend it."
