There is a second xbox account connected to my microsoft account and I can't login to the...

i created the xbox live account before they were connected to microsoft accounts so I'm unable to login since I forgot the password and I can't reset the password without access to the email.

I do have a microsoft account but its not connected to the xbox account

No the thing is I have bought the minecraft account with Microsoft and not with a mojang so it was already migrated

And I could login without it connecting with Xbox account and recently it was connecting with my Xbox account and I could not login without saying welkom to you Xbox account (this is on my pc)

Yes, I can login at the website, and the network connection is functioning fine the console downloads updates and stuff. After the hard restart, my profile is initially logged in but within a few seconds I get a message something went wrong with that same
error code. 0x80045C01.

If I do a hardreset with the network intentionally off my profile will be logged in until I restore the network connection.

Edit: Still can't login on my xbox, If I create a new account that one can login and out but not my actual account.

In the end I solved the problem my removing and readding my account to the xbox.

I don't quite understand what you mean due to them being linked to the same microsoft account they have the same email and I can't login to the original, I did chose the forgot password option on the xbox page and I still can't login to the original account() and am only being logged into the newer one(BubbaDaPunk) though I may have not followed your instructions correctly since I didn't get any questions just what my email connected to my microsoft is and it sent a code there. I also believe since they are connected to the same microsoft account they have the same password.

Unfortunately this is not possible and since your email is a Microsoft email (Live, Hotmail or Outlook) you can't switch the email to another one and have the account not be connected to that email anymore, technically.

You can switch the login emails around but you CAN'T switch TO a Microsoft email when you do this (Live, Hotmail or Outlook). You can switch to another email provider but you can't switch between Microsoft emails as they're permanently connected to that
account they were created on. For example, you can't switch this account's email login to another Microsoft account because that email is attached to a Microsoft account already.

The only solution is to start over and have him create a new account and have the account that owns all the games to be set as the my home xbox account on the xbox one so that the new account can play all the games that account owns BUT the saves and any
progress will not move over and some DLC will not share, also.
