Steps to Fix Excel Attachments Not Opening in Outlook

1. Close Microsoft Outlook and any other Office applications you have open.

2. Check if the Excel attachments are opening in protected view. Right-click on the attachment and select “Open in Protected View.” If it opens without any issues, the file might be corrupted or have links to external data.

3. If the attachments are not opening even in protected view, try running a repair on your Office installation. Go to the Control Panel, select “Programs,” then “Programs and Features.” Find Microsoft Office in the list, right-click and select “Change.” Choose the “Repair” option and follow the instructions.

4. Ensure that your anti-virus software is not blocking the opening of Excel attachments. Temporarily disable the anti-virus software or add an exception for Excel file attachments.

5. Clear the Outlook temporary files by typing “%temp%” in the Windows search bar. Delete all the files in the folder that opens.

6. If the issue persists, check if there are any pending updates for Office. Open any Office application, go to the “File” tab, and select “Account.” Click on “Update Options” and then “Update Now.”

7. If none of the above steps work, consider reinstalling Microsoft Office. Uninstall Office from the Control Panel, restart your computer, and then reinstall it.

Remember to always backup your important files before making any changes to your system.

If you continue to experience issues, reach out to Microsoft Support for further assistance.

Ensure that both Excel and Outlook are updated to the latest versions to avoid any compatibility issues and improve functionality.
