Windows 10: Email address is already taken

Trying to change the email address associated with my Microsoft account but it already has it's own Microsoft account. How do I delete that Microsoft account so I can use its email on my current one

EMAIL address is already taken - gmail account

Hi,

The error message that you receive usually occurs if the email address that you are tying to use is already registered to a different gamertag or Xbox Live profile. To better assist you with your concern, please clarify the following information:

• Are you trying to change the email address attached to your Xbox Live gamertag?
• On which device are you trying to do the process?
• Is the email address that you want to use registered as a Microsoft Account?

 

Win10 Mail - where's the address book?


That’s now the People app.
If you know the contact's name or email address & they’re listed in the People app, you can start typing the first few letters of their name or email address and Mail for Windows 10 will suggest matching contacts.

 

Mail App: Removing drop down email address suggestions


I'm not a big fan of the MS Mail program and don't really use it for serious stuff but somehow or other if I create a new email then as I start to enter the recipients address a whole load of suggestions will appear. I don't have any contacts in the People app so I'm not sure where these come from.

The question is how can I clear this list so that I no longer get the suggestions?

Thanks
