How to Fix Office Error 49dvs in Word and Excel for Mac
Question details
A Mac user receives the error code [49dvs], often displayed as the French message "Nous avons rencontré un problème. [49dvs]", and is unable to use Microsoft Office applications.
- Product
- Microsoft Office for Mac
- Device & OS
- macOS
- Scenario
- Attempting to launch and use Microsoft Word, Excel, or other Office applications on a Mac computer.
- Observed behavior
- The Office applications fail to function normally and display an error window containing the string [49dvs], blocking access to files and tools.
Before beginning, ensure your macOS is updated to the latest version and verify that your Microsoft 365 subscription is currently active.
Restart in Safe Mode and Grant Full Disk Access
Using Mac's Safe Mode helps identify background interference, while granting Full Disk Access ensures Office has the correct system permissions to operate.
Often, background utilities or strict privacy settings on macOS block Microsoft Office from verifying its license or accessing required application support files.
Shut down your Mac. Turn it back on and immediately press and hold the Shift key until the login window appears. Log in to see if the issue persists.
Click the Apple menu in the top-left corner of your screen and select System Settings (or System Preferences).
Click on Privacy & Security in the sidebar, then select Full Disk Access from the list on the right.
Find Microsoft Word and Microsoft Excel in the application list and toggle the switch to the ON position to grant them full disk access.
Remove Affected Office Container Folders
Corrupted temporary cache files within the Office container folder can trigger application errors. Removing them forces the software to generate fresh, healthy files.
Create and Test a New Mac User Profile
If the error is tied to corrupted settings specific to your current user profile, testing on a new account can bypass the issue.
Switch to WPS Office for a Seamless Mac Experience
If persistent Microsoft Office errors like [49dvs] are disrupting your workflow on Mac, consider switching to WPS Office. It provides a lightweight, highly compatible alternative for Word, Excel, and PowerPoint without complex licensing bugs.
- 1. Download the Mac installer: Visit the WPS Office website and download the installation package designed for macOS.
- 2. Install WPS Office: Open the downloaded file and drag the WPS Office application icon into your Mac's Applications folder.
- 3. Open your files instantly: Launch WPS Office and open your existing Word or Excel documents directly, no conversion required.
Frequently Asked Questions
What does error [49dvs] mean in Microsoft Office for Mac?
Error [49dvs] is typically a permission or connectivity issue. It indicates that the Office application cannot access essential system files to verify your license or launch correctly, often caused by corrupted cache or restricted macOS privacy settings.
Why is my Office error message displayed in French?
If you see 'Nous avons rencontré un problème', it may be due to regional macOS language settings, a VPN routing your connection, or a temporary fallback language issue on Microsoft's verification servers. The troubleshooting steps are exactly the same regardless of the language displayed.
Will clearing the Office container folder delete my documents?
No. Deleting the 'com.microsoft.Word' or 'com.microsoft.Excel' folders in the macOS Library only clears application cache and temporary preference files. Your saved documents, spreadsheets, and personal files remain completely safe.
Should I reinstall Office to fix the 49dvs error?
Reinstalling should be a last resort. Try restarting in Safe Mode, granting Full Disk Access, and clearing the container folders first, as these methods fix the root cause of the error much faster than a full reinstallation.
