Change the spelling of a Teams member name

Hello,

You put the Teams for free tag for this question, but it sounds like you are using Teams for business, can you please verify?

In addition, this guest user is not in your organization, right? Do you have admin access? If not, you need your Admin user to sign into Admin Center https://admin.microsoft.com > Users, and find the user and change it there. Changes can take up to 24 hours to reflect.

To change the spelling of a member's name in Microsoft Teams, you will need to update the user's name in Microsoft 365. Here are the steps you can follow:

1. Access the Admin Center: You must be a user administrator to make changes.
2. Navigate to Active Users: Go to the Users > Active users page in the admin center.
3. Select the User: Find and select the user whose name you want to change.
4. Manage Username and Email: On the Account tab, select Manage username and email.
5. Change the Name: Update the user's name in the provided fields.
6. Save Changes: After making the changes, select Done to save.

If you encounter any error messages during this process, refer to the relevant documentation for troubleshooting steps.

Once the name is updated in Microsoft 365, it should reflect correctly in Teams when you invite the user again.
