Change one oulook address to another oulook address

M3tal Daz3 is correct, if you have any Microsoft domain email address, you will delete the whole account. Any non Microsoft domain emails can be changed with no issues.

Hi!

You can change your email address and password directly from your
profile. Select "Manage how you sign in to Microsoft" and add the new email address.

Yet if you choose to remove an alias that uses a Microsoft domain such as @hotmail.com, @outlook.com, or @live.com, that alias will be completely deleted and will not be available to sign in to any Microsoft services.

Hi Jason,

We will be locking this thread, however, as
mentioned if the emails are Outlook, Hotmail or msn you cannot switch them between the accounts. You can attempt to

switch the primary alias, however you will need to leave it on the account as the secondary email.

If the email is connected to the wrong
gamertag, you can move the email over to the gamertag you do want it connected to. It will be similar to musical chairs. You will first need to free up the email you want to use on the other account by first changing that email to a 3rd email that you don't
care for (or create a new one on another website like Gmail or Yahoo just for this) and then you can move that email to the account you want it on. It could take up to 48 hours for the emails to update across all systems.

If you ever require any help with
any other issues please feel free to come back to the Xbox Forums for further assistance. You are more than welcome to start another thread detailing the issue at hand and any troubleshooting steps (if any) you’ve tried so far. We will be more than happy to
help!

Thank you

Shouldn't be an issue. You'll need to create a dummy email address in order to free up the other account. Simply follow the instructions at this link to change the address.
