As it turns out, merging two Microsoft account is currently not possible. However,
you can change the way you sign in and show up to recipients by adding aliases to your Microsoft account. An alias is like a nickname for your account that can be an email address, phone number, or Skype name. It uses the same inbox, contact list, and
account settings as the primary alias. You can sign in to your account with any alias, and you only have to remember a single password for all of them.
You cannot add an alias that is already associated with another Microsoft account. Aliases cannot be used to share information between two Microsoft accounts—the ability to link Microsoft accounts was discontinued in 2013.
Existing @hotmail.com, @live.com, @outlook.com, and @msn.com addresses can't be added as aliases.
By default, the email address or phone number that you use to sign up for your Microsoft account is considered the primary alias. Your primary alias shows up as the main account name when you view your profile information. This can be changed at any
time. To add an alias, here's how:
Follow the instructions to set up and verify your new alias. If you choseAdd email, you have the option to use an email address that you already have, or you can create a new Outlook.com email address.
