can i some how switch my microsoft email between two microsoft accounts?

Hi Mitchell709! My name is Ricardo an independent advisor ready to help you with this situation

Once you link your Outlook account to a Xbox gamertag you can't add that email to a different gamertag, you could add a different email that had never even linked to a Xbox account only

You can switch email addresses between the accounts only if they are not Hotmail, Outlook or Live emails. You can NOT switch gamertags between Microsoft accounts in any way.

See here to change emails around: NOTE that you will have to change the email of the first account to something else in order to free it up for use to change to the other account:

If you want to change the email between the two the instructions are here:
support.xbox.com/.../switch-gamertag-to-different-microsoft-account

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.

Yes you can. It's a little bit involved, so it's probably easiest I just link you to the page:

support.xbox.com/.../switch-gamertag-to-different-microsoft-account

Note that you only have to complete the 9 steps at the top. The 'notes' section is all about swapping the emails between two accounts.
