It can be frustrating when Outlook isn’t properly organizing emails, requiring manual sorting instead. To troubleshoot, consider the following steps:

1. Check the source of your emails to ensure they are compatible with Outlook.
2. Clear out any extra categories or rules you may have created that might be conflicting with Outlook’s standard sorting protocol.
3. Check Outlook’s search feature to see if the emails are searchable by subject or keyword.
4. Try and find out which version of Outlook you are using and if there may be an update available.
5. Look into third-party plugins that can help you with advanced features of Outlook.
6. If all else fails, contact Microsoft support directly.
