Fix Excel Crashing for One User When Opening Shared Workbooks
Question details
A single Microsoft 365 user experiences repeated Excel crashes and access violation errors (0xc0000005) when opening shared workbooks, despite other users accessing them without issues.

- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Attempting to open and collaborate on a shared workbook in Microsoft Excel.
- Observed behavior
- Excel crashes repeatedly, displaying an EXCEL.EXE access violation with error code 0xc0000005. The issue is tied to the specific user and follows them across multiple computers.
Ensure you have administrative privileges on your computer and your Microsoft 365 admin center credentials handy, as troubleshooting user-specific profile corruption requires administrative actions.
Perform a Complete Microsoft 365 Apps Cleanup and Reinstall
Because the crash follows the user across multiple devices, performing a clean uninstallation and reinstallation helps clear out corrupted profile data and application files causing the 0xc0000005 access violation.
A standard uninstallation often leaves behind cached data or registry keys that may be causing the crash. Using Microsoft's official cleanup utility ensures all residual files tied to the user's Office profile are removed before reinstalling.
Navigate to the official Microsoft support site and download the Microsoft Support and Recovery Assistant (SaRA) tool to completely uninstall Office.
Launch the SaRA tool, select 'Office', choose the option to completely remove the installation, and follow the on-screen prompts.
Once the tool finishes the cleanup process, restart your PC to ensure all temporary files and corrupted registry entries are cleared.
Log in to the Microsoft 365 portal with your user account, download the latest Office installer, and run it to perform a fresh installation.
Open Excel, sign in to your Microsoft account, and attempt to open the shared workbook again to verify the crash is resolved.

Create a Microsoft 365 Support Request
If a clean reinstallation does not resolve the user-specific crash, the issue may require backend intervention from Microsoft Support.
Try WPS Office for Stable Spreadsheet Collaboration
If Microsoft Excel continues to crash due to persistent user-profile errors, consider switching to WPS Office. It provides a robust, lightweight, and highly compatible alternative for opening and editing shared workbooks without the profile-syncing bugs found in Microsoft 365.
- 1. Download the installer: Visit the official WPS Office website and download the free installer for your operating system.
- 2. Install WPS Office: Run the setup file and follow the quick on-screen instructions to install the lightweight suite.
- 3. Open your shared workbook: Launch WPS Spreadsheets, navigate to your shared .xlsx file, and open it to resume collaboration immediately.

Frequently Asked Questions
Why does Excel crash with error code 0xc0000005?
Error 0xc0000005 is an access violation error indicating that Excel attempted to read or write to an invalid memory location. This is commonly caused by corrupted Office installation files, problematic add-ins, or profile syncing issues within Microsoft 365.
Why is the shared workbook crash only affecting one specific user?
If only one user experiences the crash while others can open the file successfully, the issue is typically tied to that specific user's Microsoft 365 profile or corrupted local application data, rather than the workbook itself.
Should I use a registry cleaner to fix my Excel crashing issue?
No. Microsoft strongly advises against using third-party registry cleaning tools. They are unsupported and can inadvertently delete crucial system keys, causing further instability or preventing Office apps from functioning entirely.
How can I collect event details for an Excel crash?
You can use the built-in Windows Event Viewer by navigating to Windows Logs > Application and looking for Error events related to EXCEL.EXE. Alternatively, diagnostic tools like WhoCrashed can help analyze crash dumps for more detailed insights.
