Windows 10: Need help changing email adress on microsoft windows

Need to removed educational email linked to version of windows and add my personal email

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.

Adresses in mail / person app

On two PC's I have problems when filling the TO field in the mail app when starting a new mail. These PC's are in no way related / sharing information.

• I get NO suggestion for some of the adresses in the people app; for most I do.
  
  When i click the adress book icon at the end of the address field in the new mail, I see the adresses in the list and can select it.
  
• I get suggestions for people who are NOT in my address book.
  
  How can I delete thoses suggestions and how come these adresses pop up?
