Which account do you want to use?
How can I have two accounts with the same email address?
If you see a screen asking, "Which account do you want to use?" when you sign in, it means that you have two accounts with Microsoft which use the same email address.
Account source:
The Work or school account was either created on purpose by your organization's IT department, or in rare cases, accidentally by another organization whose .com domain name matches that of your personal account.
The Personal account was either created by you directly or may have been created automatically when creating an Xbox or Skype account.
How can I get rid of the prompt?
1. Rename your personal Microsoft account
To rename your personal account you can either create a new email address (alias) or set an existing email address to be your primary alias.
Tips:
-
An alias is like a nickname for your account that can be an email address or a phone number. 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.
-
Your primary alias appears on devices, such as your Windows PC or your Xbox.
-
You may not want to rename your Microsoft account if you are part of the Xbox Developer community, or your Visual Studio or MSDN subscriptions are linked to your Microsoft account.
To rename your account, go to the Manage how you sign in section of your Microsoft account and select Make primary for one of your existing addresses, or add a new one.
2. Contact the organization
Where an organization's .com domain name matches that of your personal account, you can contact the other organization to ask them to remove your name from their email lists.
Your personal email address will not be in use or available to anyone in the other organization, but they will need to take action to prevent this error from happening.
