Sending, receiving, and organizing email in Outlook.com
Hi!
Where does this incorrect information appear? In the email address itself, in the recipient field (Name), or at the end of the sent email (signature)?
Does this problem occur on another device, such as a mobile phone?
Have you also checked if your name is correct in Account Info?
My name is correct in my profile information
Where did you access Profile Info? In Outlook Web itself or through the website https://account.microsoft.com/?
