How do I troubleshoot the issue of Outlook not properly displaying email threads or conversations?

1. Check your account settings to confirm that conversation view is enabled.


2. Check your Outlook settings to be sure nested messages and conversations are properly enabled.


3. Check your filters to ensure only relevant conversations are appearing.


4. Double-check that you have the latest version of Outlook installed.


5. Delete conversations you no longer need to clear out clutter.


6. Verify that all messages have the same subject line and any exceptions are out of sync.


7. Reset your profile back to its original state by clearing out any customization.
