This can happen if the software can’t confirm your purchase or if the activation process fails. You can fix it by checking your license status, repairing or reinstalling Office without losing your files, and if needed, contacting Microsoft support. ## Why does Microsoft Office stop working after I paid for it? Microsoft Office can become unusable after purchase or update mainly due to license validation errors or activation glitches. This happens when Office can’t verify your purchase, often because of communication issues with Microsoft's activation servers. You might see messages like: ```text Product Deactivated Your license isn’t valid ``` Symptom Another reason is that forced updates sometimes introduce bugs or corrupt files that break Office functionality. Activation problems also occur if the activation process didn’t finish properly, especially after switching devices or changing hardware. These issues can cause Office apps not to open, display errors, or switch to read-only mode despite a valid purchase. ## Before you start This guide applies to Microsoft Office 2016, 2019, 2021, and Microsoft 365 subscriptions on Windows and Mac. You’ll need administrator privileges to repair or reinstall Office. Before making changes, back up your important Office files, including templates and custom dictionaries, to an external drive or cloud storage. Check that your internet connection is stable, as activation and repair require online access. Restart your computer before proceeding to clear temporary glitches. ## How can I check if my Office license and activation are still valid? 1. Sign in to your Microsoft account at account.microsoft.com/services and verify your Office subscription or product is listed as active and not expired. 2. Open any Office app, like Word or Excel. 3. On Windows, go to File > Account and look under "Product Information" for activation status. 4. On Mac, open an Office app, click Help > Check for Updates, then go to the About section to view license details. 5. Make sure you’re signed into the Office app with the same Microsoft account that owns the license. If your license shows as expired, suspended, or unactivated, Office won’t work properly. ![A person viewing Microsoft Office activation status on a laptop screen.](https://tse1.mm.bing.net/th?q=user%20checking%20Microsoft%20Office%20activation%20on%20laptop&w=624&h=352&c=7) ## What are the safest ways to repair or reinstall my Microsoft Office? Start by backing up your important Office files. On Windows: 1. Open Control Panel and select Programs and Features. 2. Find Microsoft Office, select it, then click Change. 3. Choose "Quick Repair" and follow the prompts. This attempts to fix issues without needing internet. 4. If that fails, repeat and select "Online Repair," which takes longer and requires an internet connection. On Mac: 1. To uninstall, drag Office apps from the Applications folder to the Trash and empty it. 2. Download the installer from your Microsoft account page. 3. Run the installer and follow the prompts to reinstall Office. Reinstalling Office won’t delete your personal documents, but keep backups just in case. ![A Windows PC showing the Microsoft Office repair option in Control Panel.](https://tse1.mm.bing.net/th?q=repairing%20Microsoft%20Office%20on%20Windows%20PC&w=624&h=352&c=7) ## How do I confirm Microsoft Office is working properly again? Open an Office app like Word. It should start without error messages or activation prompts. On Windows, go to File > Account and check the license status says "Product Activated" or "Subscription Active." On Mac, check About Word or Excel for similar status. Create and save a new document to verify normal functionality. If you see no activation warnings and the apps work normally, the problem is fixed. ## What should I do if I still can’t fix my Office and want to contact Microsoft support? If repairing and reinstalling don’t solve the problem, contact Microsoft support. Before you call or chat, gather: - Your Microsoft account email - Purchase receipt or proof - Exact error messages you’ve seen Use the official Microsoft support website to start a chat or schedule a callback. When you talk to support, explain your issue clearly and list the steps you’ve already tried. They may ask to remotely access your PC or guide you through advanced troubleshooting. If the first agent can’t help, ask politely to escalate your case. Keep notes of your interactions and your case number for follow-up. ## How can I prevent this from happening again? Keep your Office and Windows or macOS updated to avoid bugs that affect activation. Always sign into Office apps with the Microsoft account tied to your license. Avoid switching devices or hardware without properly signing out and deactivating Office first. Regularly check your license status at your Microsoft account page. Keep backups of your important Office files, so you won’t lose work if you need to repair or reinstall. ## Conclusion If Microsoft Office still won’t work after these steps, Microsoft support is your best option. Have your account and purchase details ready when you contact them. Once fixed, keep your software updated and monitor your license status to prevent future problems. ## Frequently Asked Questions ### Can I lose my documents if I reinstall Microsoft Office? No, reinstalling Office does not delete your personal documents. However, it’s always wise to back up important files before making software changes. ### Why does Office sometimes say my license isn’t valid even though I paid? This usually happens due to activation glitches or temporary connection problems between Office and Microsoft’s servers. It can also occur if you’re signed into Office with a different account than the one used to buy the license. ### Is repairing Office safer than uninstalling and reinstalling? Yes. Repairing Office keeps your settings and is less disruptive. It should be your first troubleshooting step before trying a full reinstall.
