Remove ******@verizon.net

Add your Hotmail address as a verified security method first, and then remove the Verizon address from Advanced security options.

Replace the verification email

1. Go to Microsoft account Security and sign in.
2. Select Manage how I sign in.
3. Select Add a new way to sign in or verify.
4. Choose Email, enter your @hotmail.com address, and request the security code.
5. Enter the code sent to Hotmail and select Next. Confirm that the new address now appears among your verification methods. ^1^
6. Expand the old @verizon.net verification method and select Remove, then select Remove again to confirm. ^2^

Do not remove the Verizon method until the Hotmail method has been added and verified. Removing all security information can place the account in a restricted state for 30 days, during which further security and billing changes cannot be made. ^2^

If Microsoft requires a code from the inaccessible Verizon address

On the verification screen, select I don’t have any of these and follow the prompts to replace the security information. This replacement may trigger the 30-day restricted period. Microsoft Support cannot send verification codes or directly change account security details. ^2^

These steps change only the security/verification method. They do not change the primary Outlook sign-in address or email alias.
