I have already made the payment, but I cannot activate Microsoft 365.

If you have already made the payment for Microsoft 365 but are unable to activate it, there are several troubleshooting steps you can take:

1. Check Subscription Status: Ensure that your subscription is active. You can do this by going to the Microsoft 365 Admin Center and checking under Billing > Your products.
2. Sign Out and Sign Back In: Open a Microsoft 365 app, select your name or profile picture at the top, sign out, and then sign back in using your Work or School account.
3. Verify Account and License: Make sure that your account has the correct license assigned. If you’re using a Work or School account, contact your Microsoft 365 administrator to confirm that a license is assigned to you.
4. Update Microsoft 365: Ensure that your Microsoft 365 apps are up to date. Open an app like Word, go to File > Account, and select Update options > Update now.
5. Run the Microsoft 365 Sign-in Troubleshooter: This tool can help resolve sign-in issues that may be preventing activation. You can find it in the Get Help app.
6. Reset Activation State: If the above steps do not work, you may need to reset the activation state for Microsoft 365 Apps for enterprise.

If you continue to experience issues, consider reaching out to Microsoft support for further assistance.

Dear @Lâm Lê,

Thank you for reaching out to the Microsoft 365 Q&A forum community. We understand you've completed payment but cannot activate Microsoft 365. Please follow these steps to resolve the issue promptly. 

Step 1: Verify account & License 

• Ensure you're signing in with the exact Microsoft account used for the purchase. 
• Confirm a license is assigned to your account by checking your My account page. If you're using a work/school account, contact your IT admin to verify license assignment. 

Step 2: Confirm version compatibility 

• Ensure that the version of Microsoft 365 you're trying to activate matches the product you purchased. You can check which Microsoft 365 product you have. 
• Ensure your Office version (32-bit or 64-bit) matches your Windows version. Check via File > Account > About Word. Match it with your Windows system type (Settings > System > About). 
• If there’s a mismatch, run the Microsoft 365 uninstall troubleshooter to uninstall Office completely and then reinstall the correct version. Download and run the Microsoft Support and Recovery Assistant to automatically diagnose and fix activation issues. 

For more details, please refer to Microsoft’s official documentation: What Microsoft 365 business product or license do I have? - Microsoft Support 

Step 3: Sign out and back into Office 

• In any Office app (Word, Excel), go to File > Account > Sign Out. 
• Restart the app and sign in again with your Microsoft account. 

Step 4: Use private browser for activation 

• Open an InPrivate (Edge) or Incognito (Chrome) window and visit office.com. Sign in and try activating from there. 

Step 5: Check subscription status 

• Ensure your subscription is active and hasn’t expired. You can do this from the Microsoft 365 Admin Center. 

(Please note that if you are a user you will need to ask your global administrator to perform these steps) 

Please note that as a forum moderator, I don’t have access to backend tools or internal systems to investigate further, and certain settings or configurations are managed exclusively by your organization’s administrators, so I’m unable to check or make changes on that side. That said, I truly hope these suggestions help you move forward.  

Please let me know if you have any further questions or if the problem persists after trying these solutions. Thank you for your patience and cooperation.
