Hi, @reece Anderson

Microsoft accounts cannot actually be merged.

To help clarify the situation:

What exactly did you do when you were trying to remove the old email address?

Where did you make the change: Outlook.com, your Microsoft account page, Windows Settings, or somewhere else?

Did you add your dad's email as an alias, change the primary alias, or add it as security/recovery information?

Thanks!

Thanks. What is the domain of the old email address you are trying to remove, for example @outlook.com, @hotmail.com, @live.com, or something else?

This is important because if it is a Microsoft email address and you remove it as an alias from the Microsoft account, that address is permanently deleted and generally cannot be used or added back again.

Thanks!

Thanks. Do you mean the old email address ends in @outlook.com?

Also, can you still sign in to the Microsoft account using that old Outlook email address, or do you no longer have access to it?

Thanks!

Answer 1

To "unmerge" them and remove the old email, the user needs to manage the account aliases.

Steps to separate the emails:

Log in to the Microsoft account at [account.live.com/names/manage](https://account.live.com/names/manage) using the current primary email address.

Under the Account aliases section, a list of all email addresses connected to this specific account will be displayed.

Locate the correct email address that should be the main login and click Make primary next to it (if it isn't already the primary).

Locate the dad's email address or the old email address and click Remove next to it.

CRITICAL WARNING BEFORE REMOVING:

If the email being removed is a third-party address (like @gmail.com or @yahoo.com), it is perfectly safe to click Remove. It will simply disconnect from the Microsoft account, and the email itself will continue to work normally.

If the email being removed is a Microsoft domain (like @outlook.com, @hotmail.com, @live.com, or @msn.com), clicking Remove will permanently delete that email address and its inbox from Microsoft's servers. It cannot be recovered, recreated, or moved to another account. If the dad's email is a Microsoft domain, removing it will destroy his email account.To "unmerge" them and remove the old email, the user needs to manage the account aliases.

Please edit your Answer to correct some obvious copy/paste artifacts. And in the future, when doing a copy/paste from another output stream, at least take a few moments to edit your post before you hit the [Post] button.

1 -- The entire answer essentially repeats itself. After the first "CRITICAL WARNING BEFORE REMOVING:" section, the content starts over.

2 -- You pasted in the raw markdown for links instead of converting them to actual URLs.
