Fix Microsoft 365 Apps Closing on Surface Pro 11
Question details
Microsoft 365 applications unexpectedly close shortly after opening on a Surface Pro 11, although they function properly in Safe Mode.

- Product
- Microsoft 365
- Device & OS
- Surface Pro 11 (ARM-based)
- Scenario
- Opening and attempting to work in Microsoft 365 applications like Word, Excel, or PowerPoint.
- Observed behavior
- The applications become unstable and close themselves shortly after launch. AutoSave may also appear disabled prior to the crash.
Ensure your Windows 11 operating system is fully updated, as Microsoft frequently releases compatibility patches for ARM-based devices that resolve unexpected app closures.
Start in Safe Mode and Disable Office Add-ins
Use this method to determine if a faulty third-party add-in is causing Microsoft 365 to crash upon opening.
Safe Mode forces Microsoft 365 apps to bypass custom add-ins and background extensions. If the application runs perfectly in Safe Mode, an incompatible add-in is likely the culprit causing the crashes on your ARM-based device.
Press the Windows key + R to open the Run dialog. Type 'winword /safe' (for Word) or 'excel /safe' (for Excel) and press Enter.
Once the application opens, click on 'File' in the top-left corner, select 'Options', and then click on 'Add-ins' located in the left sidebar.
At the bottom of the window, ensure 'COM Add-ins' is selected in the Manage dropdown and click 'Go'. Uncheck all add-ins in the list and click 'OK'.
Close the Office application and reopen it normally. If it stays open, re-enable your add-ins one by one to identify which one is causing the crash.

Reinstall Microsoft 365 without OneNote
Use this solution if Safe Mode troubleshooting fails, as OneNote components can sometimes conflict with the rest of the Office suite on ARM processors.
Experience Crash-Free Productivity with WPS Office
If Microsoft 365 continues to experience compatibility and crashing issues on your Surface Pro 11, WPS Office is an excellent alternative. It offers a lightweight, fast, and stable environment for all your document needs without the frustrating crashes.
- 1. Install WPS Office: Download and run the free WPS Office installer directly from the official website.
- 2. Open Your Files: Launch WPS Office and easily open any existing Microsoft Word, Excel, or PowerPoint files without losing formatting.
- 3. Edit Without Interruptions: Enjoy a stable editing experience and save your work natively in standard Office formats.

Frequently Asked Questions
Why does Microsoft 365 only work in Safe Mode on my Surface Pro 11?
Safe Mode forces the Office application to load without custom settings, background extensions, and COM add-ins. If the app works in Safe Mode, the crashing is almost certainly caused by an incompatible third-party add-in rather than the core Microsoft 365 software itself.
How can OneNote cause Word or Excel to crash?
Microsoft 365 applications share numerous background services and components. If a specific OneNote synchronization module or background process encounters an error on the Surface Pro's ARM architecture, it can destabilize the entire Office suite, causing other apps to close unexpectedly.
Will I lose my files if I reinstall Microsoft 365?
No, uninstalling and reinstalling Microsoft 365 will only remove the application files. Your locally saved documents, spreadsheets, and presentations, as well as files stored in OneDrive, will remain completely untouched on your device.
