My microsoft cannot active and how to solve the problem

Dear printing neuuv,

According to your description, I understand that you are unable to activate Microsoft Office when using Word and Excel. I’ll be glad to help you troubleshoot this.

1.Could you first please share the exact activation error code you receive?

2.Visit https://www.office.com/, sign in using the same account that you use for the Excel desktop application, then open Excel and let me know whether you can sign in successfully and use Excel on the web without any activation or licensing errors.

Meanwhile, please open Word or Excel > File > Account and confirm that you are signed in with the Microsoft account or work/school account associated with your Office license.

Please also confirm whether your Microsoft 365 subscription is currently active.

• Visit this link: https://portal.office.com/account/?ref=Harmony
• Once signed in, navigate to the Subscriptions section
• There, you should be able to view details related to your active Office 365 plan.

This page will show you information such as your subscription type, billing status, renewal date, and any linked licenses.

Next please sign out of Office, close all Office applications, uninstalling and reinstalling Office, restart your computer, and sign in again.

You can also refer to this article for additional information if you encounter a similar issue: Unlicensed Product and activation errors in Office - Microsoft Support 

If the issue persists after completing the steps above, please do not hesitate to let me know, and I will be happy to assist you further.
