- Product
- Microsoft 365 (Word and Excel)
- Device & OS
- not provided
- Scenario
- Attempting to use Microsoft Word or Excel for business tasks.
- Observed behavior
- The applications crash and close unexpectedly with an error stating the application must close. Basic fixes like repairing, updating, and removing add-ins do not resolve the issue.
Ensure you have saved any recoverable work and gather details about the specific error message, as this information will be crucial for advanced troubleshooting or support tickets.
Perform Standard Office Troubleshooting
Try these common fixes first if Word or Excel crashes unexpectedly before escalating the issue.
Before contacting support, it is best practice to rule out local application issues. Outdated software, corrupted installations, or problematic add-ins are the most common culprits for unexpected application closures.
Open any Office app that still works, go to File > Account, click on Update Options, and select Update Now to ensure you have the latest patches.
Press the Windows key + R to open the Run dialog. Type 'winword /safe' (for Word) or 'excel /safe' (for Excel) and press Enter. If the apps open without crashing, a third-party add-in is likely causing the issue.
Open the Windows Control Panel, navigate to Programs and Features, select your Microsoft 365 installation, click Change, and choose Online Repair to fix corrupted files.
Contact Microsoft 365 Admin for Business Support
If standard fixes fail, the issue may be related to environment policies or deep system factors requiring business support intervention.
Use WPS Office When Microsoft 365 Apps Keep Crashing
If Word and Excel continue to crash and disrupt your workflow, consider switching to WPS Office. It is a free, lightweight suite that is fully compatible with Microsoft Office formats, allowing you to seamlessly continue your work without missing a beat while your IT department fixes the Microsoft 365 environment.

- 2. Open Your Files: Launch WPS Office and directly open your existing .docx or .xlsx files without any conversion required.
- 3. Resume Your Work: Continue editing your documents and spreadsheets immediately using a familiar interface.
Frequently Asked Questions
What causes Word and Excel to close unexpectedly with an error?
This can be caused by conflicting third-party add-ins, corrupted system files, outdated software, or complex environmental and policy conflicts in business networks.
Will reinstalling Microsoft 365 fix the unexpected error?
Reinstalling often fixes corrupted program files. However, if the issue stems from a persistent registry error, corrupted user profile, or organizational network policy, reinstallation might not resolve it.

Can I recover my work if Word closes unexpectedly?
Yes, Microsoft Office often saves a temporary backup. Open the application again to see if the Document Recovery pane appears on the left side, or check the AutoRecover file location in your settings.
