How do I fix the problem of Outlook not properly saving my email drafts when composing replies?

1. Check to see if your email drafts are saving locally to your computer, and not the Outlook server.
2. Check your account settings and make sure that your mailbox has the proper permission to keep track of email drafts.
3. If there are security settings preventing the saving, update your security settings to grant permission to Outlook for saving drafts.
4. Check for outdated Outlook software or plug-ins and ensure that you have the latest versions.
5. Manually save your drafts from time to time, as an added precaution.
