If this is an email service you pay for, contact customer service, and they will help you. If it's one you don't pay for (if it's hotmail/MS live as it seems to be), their even taking the time to read your inquiry about it has a cost/benefit ratio >1, and your inquiry will likely to be sent directly to /dev/null or whatever the equivalent is on Windows Server.
This is one of the drawbacks of "free" services.
It's 2018, and even Microsoft won't have left an internet-facing service vulnerable to whatever kind of cracking you're capable of, so you can forget that, too. Or you can not forget it and go to Federal prison.
