Managing personal Outlook.com account settings, security, and privacy
Welcome Richard Hunt,
I understand how frustrating this has been, especially after being redirected several times without finding an answer that addresses the actual issue.
Could you clarify where you are seeing the strange display name? For example, does it appear next to your email address when you send a message, on your Microsoft account profile, or only when another person receives an email from you?
In the meantime, if this is a personal Outlook.com account, please check the display name saved to your Microsoft account:
- Sign in to your Microsoft account and open your profile information.
- Check whether the displayed name is correct.
- If it is incorrect, select “Edit name”, enter the correct name, and select “Save”.
Microsoft notes that this display name is used when you send emails and that a change may take up to 24 hours to appear everywhere. How to change your Microsoft account name or address
Looking forward to your update.
