1. Press Windows + R keys to open the Run tool.
2. Type “outlook.exe /resetnavpane” and press ENTER.

Solution 3: Repair Microsoft Outlook Data Files

If your Outlook data files are corrupted, you can use the built-in Inbox Repair Tool (SCANPST.EXE) to fix them.

1. Go to the Outlook installation directory.
2. Look for the SCANPST.EXE file and double-click on it.
3. Follow the on-screen instructions to repair the data files.

Solution 4: Repair Microsoft Office Application

If the issue persists, repairing the Office application may help.

2. Open the Control Panel, search for “Programs and Features.”
3. Find Microsoft Office in the list and click on it.
4. Click “Change,” then select “Repair” and follow the prompts.

If repairing does not resolve the issue, you may need to uninstall and reinstall Microsoft Office.

1. Download Microsoft Support and Recovery Assistant utility.
2. Run SetupProd_OffScrub.exe.
3. Follow the instructions to remove Office and reinstall it.

If a third-party add-in is causing the issue, disable it to resolve the problem.
