Perform an Online Repair for Microsoft 365
Running an Online Repair can fix corrupted installation files that cause the applications to crash or trigger the repair prompt.
Windows includes a built-in repair tool for Office applications. The Online Repair option comprehensively checks and replaces missing or corrupted files.
Press Ctrl + Shift + Esc to open Task Manager. Locate any running Microsoft 365 processes, right-click them, and select 'End task'.
Click the Start menu, type 'Control Panel', and open it. Navigate to 'Programs' and then click on 'Programs and Features'.
Scroll through the list to find your Microsoft 365 installation. Right-click it and select 'Change'.
In the dialog box that appears, select 'Online Repair' (not Quick Repair) and click 'Repair'. Follow the on-screen prompts to complete the process.
Run the Microsoft Support and Recovery Assistant
This official diagnostic tool can automatically identify and fix complex licensing, update, and installation issues.
Completely Uninstall and Reinstall Microsoft 365
If repairs fail, a clean installation is the most effective way to resolve persistent background process or update conflicts.

Frequently Asked Questions
Why do my Microsoft 365 apps close immediately after opening?
This is often caused by a corrupted Office installation, an outdated application version, licensing sync errors, or interfering background processes. Running an Online Repair usually resolves the issue.
Will I lose my documents if I run an Online Repair?
No, running an Online Repair or even completely reinstalling Microsoft 365 only affects the application files. Your personal documents, spreadsheets, and presentations will remain safe on your computer.
Can I run Microsoft 365 as an administrator to bypass the crash?
Sometimes, running the app as an administrator can bypass permissions-related crashes. Right-click the Word or Excel application shortcut and select 'Run as administrator' to test if this temporarily resolves the issue.
How do I fix unexpected page borders in Word?
Unexpected page borders are usually a separate document formatting issue, not related to an app crash. You can remove them by going to the Design tab, selecting Page Borders, and choosing 'None' in the Borders and Shading dialog.
