How to Fix Microsoft Office Not Opening Access and Excel Files
Question details
The user is unable to open Access (ACCDB) and Excel (XLSX) files due to serious application errors and is seeking ways to troubleshoot file corruption, upgrade their Office version, or purchase technical support.
- Product
- Microsoft Office (Excel, Access, Microsoft 365)
- Device & OS
- not provided
- Scenario
- Attempting to open existing spreadsheet and database files within Microsoft Office applications.
- Observed behavior
- The Office applications fail to open the files, sometimes displaying a message that the file caused a serious error the last time it was opened. This indicates either application instability or file corruption.
Before beginning any troubleshooting or upgrading your Office suite, locate your ACCDB and XLSX files in your file explorer and copy them to a secure external drive or cloud storage to prevent accidental data loss.
Test for Application vs. File Corruption
Determine whether the issue lies with the Microsoft Office applications themselves or if your specific files have become corrupted.
When multiple files are affected simultaneously, it is often an issue with the Office application rather than the files. Creating brand new files can help isolate the root cause.
Launch Microsoft Excel or Microsoft Access directly from your Start menu without clicking on a specific saved file.
Click on 'Blank workbook' in Excel or 'Blank database' in Access to create a new, empty file.
Save the new file to your desktop, close the application completely, and then double-click the newly saved file. If it opens without errors, your older files may be corrupted. If it fails to open, your Office application requires repair or reinstallation.
Contact Microsoft Support for Assistance
Reach out directly to Microsoft's official support channels to purchase technical assistance or troubleshoot serious application errors.

Frequently Asked Questions
Will installing a newer version of Microsoft 365 overwrite my existing files?
No, installing or upgrading Microsoft 365 applications will only update the software programs. Your personal files, such as ACCDB and XLSX documents, will remain intact on your hard drive. However, it is always a best practice to back up your files before performing software upgrades.
Does Microsoft 365 Business Apps include Microsoft Access?
Yes, Microsoft Access is included in Microsoft 365 Business plans for PC users. Even if the Access icon is not prominently displayed on the checkout or download page, the application is bundled with the standard desktop installation for Windows.
What does it mean when opening a file causes a 'serious error'?
This error typically indicates that the application crashed abruptly the last time it tried to process the file. It can be caused by severe file corruption, conflicting add-ins, or a damaged Office installation. Testing the application with a brand-new, blank file helps determine if the software or the specific file is the culprit.
