How do I troubleshoot the issue of Outlook not properly formatting my emails with HTML or rich text?

1. Check if you are using the correct version of Outlook.
2. Ensure your email account is set up properly and all settings are correct.
3. Check if you are using Outlook correctly and not exceeding the email sending limits.
4. Try using basic HTML rather than rich text.
5. Look into increasing the font size instead of relying on HTML.
6. Contact Microsoft Tech Support if needed.
