Verifying the Display Name Change

After changing the display name, it's a good idea to verify that the change has taken effect. You can do this by sending a test email to an external email address.

To send a test email, click on New Email in the Outlook desktop app or the Compose icon in the web-based Outlook. In the To field, enter an external email address (like your personal email). Click on Send. Once the email has been sent, check the sent email's subject line. If the display name has been changed successfully, you should see the new display name there.

Remember, consistency is key in effective communication. Changing the display name in your shared mailbox ensures that all outgoing emails present a unified and professional image, enhancing your organization's email etiquette.
