Windows 10: Deleting old email addresses

How can I delete old email addresses for friends who have changed theirs? When I try to send them an email the system summons up the old dead one.

Delete old email sign in address

Hi,

Difficulties verifying the old security details in your Microsoft account may result in errors canceling or removing the profile. For us to rectify the account removal concern, we'd like to verify the following information:

• Where exactly are you prompted to sign in with the old email address?
• Have you tried resetting the password for the old account to recover it?
• Were you able to log in successfully on your account online?
• Have you made any significant changes to your account prior to this happening?
• What troubleshooting steps have you taken so far?

Your reply is highly appreciated.

 

Windows 10 Store Application -- old email address

Hi there,

I have already tried a lot of suggestions on this to no avail -- please help.

When I am trying to download a game from the store app a pop up asking me to verify my password for an old email address keeps coming up. This email address is not listed in my user account -- it was deleted three months ago. I have tried entering the
password for the old email address but it won't accept it and another message comes up saying there is a problem at their end and to try again later.

 

Auto Suggest - Old email addresses

Hello,

Thank you for posting your query in Microsoft Community.

I understand your concern. There is, however, no setting in Mail app to disable the auto-complete setting, you can certainly accomplish this in Outlook web app on your system. Refer to the following steps to do so:

• Sign in to Outlook Web App, and in the To, Cc, or
  Bcc lines, start typing part of the name you want to remove from the Auto-Complete List. For information about how to sign in to Outlook Web App, see
  
  Sign in to Outlook Web App.
  
  
• If the entry you want to remove is highlighted, choose Delete. If the entry you want to delete is not selected, use the Up Arrow and Down Arrow to navigate to the entry you want to delete, and then choose
  Delete.

For more information, please refer to the following article:
