Used recommended route to add a new phone number for 2FA email log in. Under additional methods no ability to add new number. Unable to replace old defunct number so deleted it - now cannot add any contact number on my log in security. Cannot verify who I am so locked out of outlook emails on Laptop.

Can anyone help?

    Hello,

    When adding security information, you can register only one phone number.

    So if the option to add a phone number does not appear, you will need to add a newly created email address or add an authentication app such as Microsoft Authenticator.

    Microsoft account security info & verification codes

    Also, if you delete all of your old security information before adding new ones, a 30‑day waiting period will be triggered.
    What does “Security info change is still pending” mean?
