Hotmail/Live.com changed their mailto: email handler. It used to be:


Where the %s gets replaced with mailto:email@blah.com by the browser when you click on mailto: links.

So going to https://mail.live.com/secure/start?action=compose&to=mailto:rawr@gmail.com will open the compose mail page pre-populated with rawr@gmail.com in the To field. However this is no longer working and I can't figure out the current one, can you please help me?

  • Craigslist appears to using: https://mail.live.com/default.aspx?rru=compose&to=TO&subject=SUBJECT&body=BODY which is no longer working either. – Stephen Ostermiller Oct 28 '16 at 17:28

This then has the following compose screen:

    Thank you Stephen for sharing this! However it doesn't work in Firefox. Firefox prefixes the email with mailto: so in my test it was mailto:TO@EXAMPLE.COM which caused it to not load :( – Noitidart Oct 31 '16 at 16:20

    You must have an extension installed that is doing that. Firefox shouldn't be touching https URLs embedded in a href. It works fine in Firefox for me. – Stephen Ostermiller Oct 31 '16 at 16:23
