Windows 10: I want to change my account's email adress

Hello,My current Microsoft / Office 365 account is linked to an old email adress of mine. I want to change that to another existing email adress outlook, so I can delete the old one. But somehow it seems I can't?

Changed Microsoft account email adress, can't login to PC

So I changed my email adress (added a new one, changed to primary and removed the old one) for my Microsoft account using my laptop. Everything worked fine there.

Now I want to log in to my desktop machine and it won't let me because it's still linked to my old email adress. Requesting a password change does not work since it just resets the password for my laptop, but not my desktop.

All my previous passwords do not work either.

I got access to the machine as administrator via some cmd trickery but I still want to log in to my "old" account obviously.

Any suggestions?

Can I somehow change the email adress registered to this "local microsoft account" to link it up with my actual one?

//Edit:

This is weird. I just tried to convert the local account I created to a Microsoft account using my new email adress and I couldn't because "This account is already in use on this PC" or something. So it HAS a reference to my new email adress but it won't
let me sign in with my current OR old password.

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.
