Question details

Excel crashes with error 0xc0000005 when specific users attempt to open workbooks.

Product: Microsoft 365 Excel
Device & OS: not provided
Scenario: Opening workbooks from network locations or desktop directories.
Observed behavior: Excel crashes abruptly with error code 0xc0000005, and the issue follows the specific user profile across different computers.

Before you start

Verify whether the issue occurs for all users on the same machine or follows specific user accounts, as this error often indicates profile-level permissions or synchronization issues.

Solution 1Recommended

Contact Your Organization's IT Administrator

Since the error follows specific user profiles across different devices, it requires account-level investigation by a system administrator.

Because this error migrates with the user account rather than staying isolated to a single PC, standard local troubleshooting (like repairing Office or reinstalling Windows) is unlikely to work. It strongly suggests Active Directory, user profile corruption, or roaming profile configuration issues.

Document the issue

Record the exact error code (0xc0000005) and note the specific network locations or files that trigger the crash.

Test on a different machine

Log in to a completely different computer using your credentials to confirm that the crash still occurs, which proves it is an account-level issue.

Report to IT Support

Provide these details to your IT department so they can investigate potential user profile corruption or adjust your account policies.

Account Privileges Required: End-users typically cannot fix roaming profile corruption on their own due to restricted network administrative privileges.

Solution 2

Create a Support Ticket in Microsoft 365 Admin Center

If you are an administrator, you can escalate the issue directly to Microsoft Support to resolve complex profile-level crashes.

Free Microsoft Office alternative

Use WPS Office as a Reliable and Stable Alternative

Frequently Asked Questions

What does Excel Error 0xc0000005 mean?

Error 0xc0000005 is generally an access violation error in Windows, occurring when an application tries to access memory it shouldn't. In this specific scenario, it is triggered by conflicts or corruption within network user profile data or account permissions.

Why does the error follow my user profile to other computers?

If the issue happens on multiple computers but only for your account, it indicates that the problem lies within your roaming network profile, corrupted user settings, or specific account permissions synced via Microsoft 365, rather than a local hardware or software fault.

Can I fix this error without contacting my IT department?

Because the error is linked to your specific user profile on the organizational network or Microsoft 365 tenant, resolving it almost always requires administrative access to reset the profile, check network logs, or adjust account configurations.
