can not add mobile number to my outlook account for 2FA

For personal Microsoft accounts such as Outlook.com, adding a new phone number as a sign-in or verification method may no longer be available. That is why the page only shows Add email and not an option to add a mobile number.

Supported alternatives are:

1. Go to the Microsoft account Security tab at https://account.microsoft.com/security.
2. Select Manage how I sign in.
3. Select Add a new way to sign in or verify.
4. Add one of the available methods, such as:
   • a recovery email address
   • Microsoft Authenticator
   • a passkey

Microsoft states that the option to add a new phone number may not be available for some personal accounts, and accepted Microsoft Q&A answers for the same scenario confirm that phone numbers can no longer be added as a new security method for personal Microsoft accounts.

If the goal is stronger 2FA for the account, Microsoft Authenticator or a recovery email is the current supported path.
