Managing personal Outlook.com account settings, security, and privacy
Hello Kristjan Haraldsson,
I understand that you cannot access your Microsoft account because the verification email no longer works, and you would like to register a mobile number instead.
Please note that this is a user-to-user forum, so contributors cannot access accounts, verify ownership, or change security information.
The Q&A Assist answer provides the correct main options. Have you had a chance to try those steps?
I would also like to add that the option to register a phone number may not appear for every Microsoft account. Depending on the available security methods, you may instead be offered another email address, Microsoft Authenticator, or a passkey. Also, if all security information must be replaced, the account enters a 30-day restricted period, although some services may remain accessible during that time.
Could you provide the exact message displayed when you try to sign in, without posting your email address, phone number, or verification codes?
