Hello mRb&
Hi, I'm Karl and will be happy to help you today.

To contact Outlook.com support, log into your Outlook.com account using a browser and click on the ? (top right)

#3 - Proceed accordingly
The following is a standard reply I give to those who ask about a sudden increase in <spam> and <unexpected> log in attempts describing how email addresses / passwords are harvested which you may find of interest
The usual source of a sudden increase in failed login attempts or spam mail received is that the email address was harvested by a hacker who breached a data base on a website where you subscribed to something. That database gets repeatedly sold to other hackers/spammers on the dark web.
Many people think that hackers penetrate the actual Microsoft servers to gain access to email accounts when that isn't the case. Instead they gain access to an actual account via any number of other ways including phishing emails.
You can check to see if the email address comes up on a breached database on the following website created/run by Microsoft MVP Troy Hunt.

*** if you find that the email address was on a breached website where a password was also entered, what you really do want to do is make sure that the same email address/password combination is NOT being used on other sites (i.e. Social Media, Facebook, Paypal, Amazon etc) and if that password is still the one being used on your email account - make sure to change it immediately. Not a question of <IF> a hacker will test those account(s) - just a matter of <WHEN>
