Using classic Outlook for Windows in business environments
You may refer to the AI's previous response for the recommended troubleshooting steps.
Additionally, you can also try to reset all Outlook views if multiple folders are affected:
-Close Outlook completely > Press Windows + R > Type: outlook.exe /cleanview > Press Enter.
This resets all custom Outlook views back to the defaults. Please note that any custom views you previously created will be removed.
If the issue remains, to better understand your situation, could you please share some information:
- A screenshot of the changed Outlook view.
- Whether the change affects only the Inbox or all folders.
- Your Outlook version (File > Office Account > About Outlook).
I look forward to you response.
