Hi, I'm John! I will help you with this.
To help narrow down the issue:
- Can you let me know the exact error message you’re seeing in Excel when it says the program has expired?
- May I know what troubleshooting steps have you already taken? This will help me avoid recommending them again.
In the meantime, Microsoft has a helpful guide that walks through the different error messages and how to fix them. You can check it here: https://support.microsoft.com/office/a-subscription-notice-appears-when-i-open-a-microsoft-365-application-4cabe32c-f594-4c0e-9191-3d3ade10cceb
Just select the error that matches what you’re seeing and expand it for the steps.
If the issue persists, please provide more details by answering my questions.
