Run an Office Quick Repair
Use the built-in Windows repair tool to quickly fix corrupt Office files causing Excel or Outlook to crash.
A Quick Repair scans your Microsoft Office installation for corrupted files and replaces them without requiring an internet connection. This is typically the fastest way to resolve recurring crash errors in Office applications.
Reboot your PC to ensure no hidden Office background processes are currently running and interfering with the repair process.
Navigate to Windows Settings or Control Panel, and click on 'Apps' or 'Apps and Features'.
Scroll through the application list to find your Microsoft Office installation. Click on it and select the 'Modify' button.
Choose the 'Quick Repair' option from the prompt window and click 'Repair'. Wait for the process to finish, then test Excel or Outlook.

Check for Conflicting Security Software
Identify and temporarily disable security or encryption software that might be incorrectly terminating Office processes.
Completely Uninstall and Reinstall Office
Perform a clean installation of Microsoft Office to resolve deep-rooted software corruption that standard repairs cannot fix.

Frequently Asked Questions
Why does Excel repeatedly say it has encountered a problem and needs to close?
This error typically occurs due to corrupted Office installation files, outdated application versions, conflicting third-party add-ins, or aggressive antivirus software interfering with the program's normal operations.
Will running an Office Quick Repair delete my personal files?
No, running an Office Quick Repair or Online Repair from the Control Panel only targets and fixes the core application files. It will not delete, alter, or move your personal documents, spreadsheets, or emails.
How can I recover my unsaved work if Excel keeps crashing?
To minimize data loss, try to enable the AutoSave feature and frequently save manually using Ctrl+S. If Excel crashes unexpectedly, look for the Document Recovery pane on the left side of the screen when you reopen the application to restore any autosaved versions of your work.
What should I do if the Quick Repair doesn't fix Outlook crashing?
If a Quick Repair does not resolve the issue, you should check for interfering third-party security software, update your Office suite, or perform a complete uninstallation using Microsoft's official removal tool before reinstalling it fresh from your Microsoft account.
