Question details
The user needs to resolve an issue where Microsoft 365 applications like Word and Outlook crash and close immediately after displaying an error.

- Product
- Microsoft 365
- Device & OS
- Windows
- Scenario
- Attempting to use Microsoft Office applications after a system upgrade or when dealing with damaged installation files and add-ins.
- Observed behavior
- The Office application displays an error message stating it encountered a problem, and then automatically closes, preventing the user from working.
Before making changes or uninstalling your Office suite, ensure you back up all critical files, including exporting your Outlook contacts and PST data to a secure folder.
Run an Office Quick Repair or Online Repair
Use the built-in Windows repair tool to fix corrupted Office program files without affecting your personal documents.
Windows includes a built-in repair utility specifically for Microsoft Office installations. Quick Repair runs locally and fixes most common issues, while Online Repair downloads fresh installation files from Microsoft's servers to completely replace damaged components.
Press the Windows key, type 'Control Panel' in the search bar, and press Enter to open it.
Click on 'Programs', then select 'Programs and Features' to view the list of installed software on your computer.
Scroll down to find 'Microsoft 365' or your specific Office version. Right-click on it and select 'Change'.
Select 'Quick Repair' and click the 'Repair' button. Wait for the process to finish and test your apps. If the apps still close, repeat these steps and select 'Online Repair' instead.

Launch Office Apps in Safe Mode
Start Word or Outlook in Safe Mode to determine if a malfunctioning third-party add-in is causing the application to crash.
Uninstall and Reinstall Microsoft 365
Perform a clean installation of the Office suite if repair tools and Safe Mode fail to stop the applications from closing.
Try WPS Office for a Stable, Crash-Free Experience
If Microsoft Office applications continue to close unexpectedly or run into persistent installation errors, consider switching to WPS Office. It is a highly stable, lightweight, and free office suite that runs flawlessly on Windows.
- 1. Download WPS Office: Visit the official WPS Office website and click the download button to get the free Windows installer.
- 2. Install in Seconds: Run the downloaded file. The lightweight installer will complete the setup process in just a few clicks.
- 3. Open Your Files: Launch WPS Office and directly open your existing Word documents, Excel spreadsheets, and PowerPoint presentations.

Frequently Asked Questions
Why do Microsoft Office apps close immediately after showing an error?
This commonly happens due to corrupted application files, conflicts with third-party COM add-ins, or system inconsistencies following a recent Windows OS update. When the application cannot load necessary background components, it forces a shutdown to prevent further errors.
Will running an Office Repair delete my documents or emails?
No. Running a Quick Repair or an Online Repair from the Windows Control Panel only replaces or fixes the core program files and registry entries required for Microsoft 365 to function. It will never touch or delete your personal Word documents, Excel workbooks, or Outlook data.
How do I safely back up my Outlook data before reinstalling?
To back up Outlook, open the application and navigate to File > Open & Export > Import/Export. Choose 'Export to a file', select 'Outlook Data File (.pst)', check the top-level folder to include all subfolders, and save the exported PST file to a safe location such as an external drive or cloud storage.
