Microsoft Account Email

This can only work if your emails are NOT hotmail, outlook or live emails as those are Microsoft email addresses. That may be the cause of your problem. You can not change TO an email that is a Microsoft email. You can change a Microsoft email to any other
non Microsoft email, though.

Please see this page on how to change the emails if you don't have those emails as your current primary ones:

Hi there

Create a junk email address, then create an alias on the email in the account you want to this junk email address.

then make that alias the primary email. This will then free up your email to be used in another account.

I changed my microsoft account email 1-2 days ago so the friend I with wouldn't have my email.
It worked he got everything but when I logged into my microsoft account on xbox it wouldn't allow me to connect to xbox live, no games would let me play online, I can't even access my profile page. Please help me fix this.

I suppose you speak about gameshare feature, that is intended for family members inside the same home, not for friend, this is against terms and conditions
