Having trouble with Microsoft Office crashing, freezing, or refusing to open on your Android phone or tablet can really slow down your workday. Fortunately, you can fix most app issues quickly by clearing the app cache, checking for pending updates, or restarting your mobile device.
Here is how to get your productivity back on track with seven proven solutions for fixing Microsoft Office on Android.
Why Is Microsoft Office Not Working on Android?
Before jumping into the fixes, it helps to understand what causes these frustrating glitches. Most of the time, the issue stems from corrupted temporary files, an outdated app version, or a lack of storage space on your device. Whether you use Word, Excel, PowerPoint, or the all-in-one Microsoft 365 app on Google Play, these common triggers can disrupt your workflow.
7 Ways to Fix Microsoft Office on Android
1. Restart Your Android Device
It sounds simple, but a standard reboot clears your phone’s temporary RAM and shuts down background processes that might be conflicting with Microsoft Office.
- Press and hold your phone’s Power button.
- Tap Restart (or Power Off, wait 30 seconds, and turn it back on).
- Open Microsoft Office again to see if it works.
2. Clear the App Cache and Data
Over time, corrupted cache files build up and cause apps to freeze or crash. Clearing them gives the app a fresh start without deleting your saved documents.
- Open your Android Settings.
- Tap Apps (or Apps & Notifications).
- Find and select Microsoft 365 (Office) or the specific app (like Word or Excel).
- Tap Storage & cache.
- Tap Clear Cache, then tap Clear Storage (Note: Clearing storage may require you to sign back into your Microsoft account).
3. Update the Microsoft Office App
Running an outdated version of Office on a newer Android OS version often leads to compatibility bugs.
- Open the Google Play Store.
- Tap your profile icon in the top right corner.
- Tap Manage apps & device.
- Under Updates available, look for Microsoft Office and tap Update.
4. Check Your Internet Connection
Many Microsoft Office features require an active internet connection to sync files to OneDrive or verify your Microsoft 365 subscription. Toggle your Wi-Fi off and on, or switch between mobile data and Wi-Fi to ensure your network isn’t the problem.
5. Uninstall and Reinstall the App
If core system files within the app have been damaged, a clean installation is often the best remedy.
- Long-press the Microsoft Office icon on your home screen or app drawer.
- Tap Uninstall.
- Visit the Google Play Store Official Page to download and install the latest version securely.
6. Free Up Storage Space
Android apps need breathing room to operate correctly. If your phone’s internal storage is almost full, Microsoft Office may crash when trying to save or load large documents. Delete unused apps, clear large files, or move photos to cloud storage to free up space.
7. Update Your Android Operating System
If your operating system is severely outdated, it may no longer support the security protocols required by modern Microsoft apps.
- Go to Settings > System > System Update (paths vary slightly by manufacturer like Samsung or Google Pixel).
- Download and install any available software updates.

Frequently Asked Questions (FAQs)
Q: Will I lose my saved documents if I clear the Microsoft Office app data?
A: No. As long as your documents were synced to OneDrive or saved directly to your phone’s local storage folders, clearing the app cache or data will not delete your files. However, make sure your work is synced before doing a complete reinstall.
Q: Why does Microsoft Office keep crashing on my Samsung phone?
A: Frequent crashes on Samsung devices are usually caused by background RAM management or outdated WebView components. Ensure your phone’s system software and Android System WebView are fully updated via the Google Play Store.
Q: Do I need a paid subscription to use Microsoft Office on Android?
A: Viewing and basic editing of documents is generally free. However, advanced formatting features and large cloud storage capacities require an active Microsoft 365 subscription.
Q: Can I use Microsoft Office offline on my Android device?
A: Yes. You can view, edit, and create documents offline. However, the changes will only sync to your Microsoft account once your device reconnects to the internet.
Q: What should I do if none of these fixes work?
A: If the app still refuses to work, visit the official Microsoft Support Website to report the bug or check for ongoing server outages affecting mobile users.
