Windows 10: Can someone open a Microsoft Account using my email address?

I am sure an email I received about suspicious activity log in related to a Microsoft Account using my email address was a potential fraud and I binned it straight away.But can someone open such an account?If so, is there a way to prevent it?Thanks

Unauthorized Emails from my account?

It is more than likely that your email account was hacked, either by a virus sniffing your password, or just simply hacked.

Either way, change your password on your email account. Unfortunately the damage by already be done. They already have your contact list and your email address associated with that contact list. There is nothing stopping them from sending out emails using their own SMTP servers to everyone on your contact list and claiming the emails are from your email address. They don't actually have to have access to your yahoo account or even any yahoo server to send emails to people that come from your address.

 

Unauthorized Emails from my account?

Embarrassingly, everyone on my email list received spam originating from my account, which is Yahoo based. A scan with MSE found two trojans, a Java/Rowindal.A and a Downloader:Java/OpenStream.W.

Are these the source of my unwanted email traffic? Would someone opening this email be infected with the same problems? Could there be more dangerous underlying threats.

Hell, I have quite a few high dollar clients in my list. I always treat people's addresses like they were unlisted numbers, and don't send frivolous "Hey how are ya" junk. This is mortifying.*Eek!

 

I want to change my Microsoft Account email address to my current email address.

The problem is the website will not let me add my current email address, saying, "this address is already taken. Choose another." It will not let me remove my current Microsoft Account email address. My current Microsoft Account email address will soon be invalid. The Microsoft phone support bot won't let me talk to a person, and suggests I go to the online help, which directs me to try the steps which don't work as described above. How can I get help? windows 10.
