Having trouble verifying a new email address I've added

Use the Microsoft account alias and security pages to re-trigger verification and ensure the new address is correctly added and set as primary.

1. Confirm the new email is added as an alias
   1. Go to Manage how you sign in to Microsoft: https://account.live.com/names/manage ("Edit account info").
   2. Sign in with the email/phone that already works.
   3. Under Account username / aliases, check that the new email address appears.
   4. If it does not appear, select Add email and follow the steps to add it as an alias.
2. Re-send and complete the verification for the new email
   1. On the same Manage how you sign in to Microsoft page, look for a Verify button next to the new email.
   2. Select Verify, then Send email.
   3. Open the inbox for the new email address and find the verification message.
   4. Click the verification link in that email. It may open a generic profile/info page, but as long as it completes without error, the alias should become verified.
3. Check that the alias is actually verified
   1. Refresh the Manage how you sign in to Microsoft page.
   2. Confirm that the Verify button is gone and the new email shows as verified (no warning or verify prompt).
4. Make the new email the primary alias
   1. Still on Manage how you sign in to Microsoft, select Make primary next to the newly verified email address.
   2. If desired, remove the old email by selecting Remove next to it (note the warning: removing a Microsoft-domain alias like @outlook.com, @hotmail.com, etc. permanently deletes that alias and it cannot be reused on another Microsoft account).
5. If verification keeps failing or the link seems to do nothing
   1. Try opening the verification link in a different browser or an InPrivate/Incognito window while signed in to the correct Microsoft account.
   2. If prompted to verify identity but the code is going to an old/defunct address, choose I don't have any of these on the verification screen and follow the prompts to replace the security information with a current email or phone. Be aware that replacing all security info can put the account into a restricted state for up to 30 days.

Once the alias shows as verified and is set as primary, it becomes the main email for sign-in and for receiving verification codes (along with any additional verification methods configured).
