Kişisel Outlook.com hesabı ayarlarını, güvenliğini ve gizliliğini yönetme
If you still know the password but no longer have access to the old phone number, select “I don't have any of these” or “I don't have access to these options” when prompted for verification.
If Microsoft then directs you to the account recovery form, complete it with as much accurate information as possible. If you are unsure about the name or other account details, provide the information you believe was originally associated with the account.
If two-step verification is enabled and you don't have access to any of the available verification methods, unfortunately, the Microsoft support team cannot bypass this security requirement or manually recover the account.
