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This error typically occurs due to corrupted Office installation files, outdated application versions, conflicting third-party add-ins, or aggressive antivirus software interfering with the program's normal operations.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.
