Office 365 apps keep showing “Product deactivated” despite valid licens

I’m facing an issue where my Office 365 apps (Word, Excel) randomly show a “Product deactivated” message, even though my Microsoft 365 license is valid and assigned correctly in the admin center. If I sign out and sign back in, it works temporarily, but the message returns after a few hours.

I’ve already tried online repair, reinstallation, and verified that activation is done through Microsoft 365 sign-in. There are no proxy or firewall restrictions affecting the connection.

Any support ?

    Dear Torres Julie
    Welcome, and thank you for sharing your issue in the Q&A forum.

    Based on the information you’ve provided, I understand that you're experiencing a recurring “Product deactivated” message in Office 365 apps such as Word and Excel, despite having a valid Microsoft 365 license that is correctly assigned in the admin center. You've already attempted several troubleshooting steps, including online repair, reinstallation, and signing out/signing back in, and confirmed that there are no proxy or firewall restrictions affecting connectivity.

    According to my research, Microsoft has published a detailed article that may help resolve this issue: Product deactivated troubleshooting guide

    In addition, to better understand the root cause, could you please provide a screenshot of the “Product deactivated” message when it appears? If possible, include the top-right corner of the application window where the signed-in account is shown. This will help us verify the activation context and identify any potential account-related conflicts.

    If you’d prefer not to share these details publicly, you’re welcome to respond privately. I’ll follow up with a secure message to collect the necessary information.

    I hope these options provide clarity and help you move forward with resolving the issue. Please review the steps at your convenience, and don’t hesitate to reach out with any additional questions. I’m always here to assist you.
