For personal Microsoft accounts, Microsoft now says you can no longer add a phone number as a new security method. Their current support article states: “For increased security, you can no longer add a phone number” when adding a new way to verify sign-in.

https://support.microsoft.com/account-billing/microsoft-account-security-info-verification-codes-bf2505ca-cae5-c5b4-77d1-69d3343a5452

See the first and last items in the gray text box.

You can still use the other options offered though, such as email, authentication app or passkey.

For a personal Microsoft account, the missing Add phone number option is often expected now. Microsoft states that when adding a new way to sign in or verify, the option to add a new phone number may not be available. Instead, available methods can include a recovery email address, Microsoft Authenticator, or a passkey.

If the goal is to check what sign-in methods are available:

Go to https://account.microsoft.com/security.
Select Manage how I sign in.
Select Add a new way to sign in or verify.
Check which methods are offered for the account.

If Phone does appear there:

Select Phone.
Enter a mobile number.
Complete the verification prompt.

Important checks:

VOIP numbers cannot be used for sign-in or verification codes. A mobile number is required.
If a message says the number is already linked elsewhere, a phone number can only be added to one Microsoft account at a time.
If the number was only recently added to another account, the documented option is to use a different mobile number.
If text verification fails with “We cannot send a text message to this number”, avoid repeated requests because unusual activity can trigger a temporary block.

If the account does not show any phone option, use another supported recovery/sign-in method such as:

recovery email
Microsoft Authenticator
passkey

The “server is not up to date” part is not identified in the available Microsoft guidance for this issue. The documented behavior is tied to account security method availability, not server version.

If access to the account is blocked by this issue, Microsoft’s support guidance is to use the sign-in helper or Contact Support. Support agents cannot change account details directly.
