Excel Upload on BusEiness Basic brings me back to Work sign in and authication verify, sheet shows as unlicenced

Hi Tom,

Thank you for reaching out and for providing the details of your issue.

Based on the information you shared, the behavior you're experiencing appears to be related to the Microsoft 365 Business Basic license assigned to your account rather than the Excel file itself. Microsoft 365 Business Basic includes access to Excel on the web and mobile devices, but it does not include licensing for the Excel desktop application installed on Windows.

As a result, when you open an existing workbook in the desktop version of Excel, the application checks whether the signed-in account has a license that includes the desktop apps. If the account is licensed with Business Basic only, Excel may repeatedly prompt you to sign in or verify your account and may display an "Unlicensed Product" message. In this case, the workbook itself is not unlicensed; the message refers to the desktop version of Excel being used to open the file.

To use your Excel files, you can consider the following options:

Option 1: Use Excel for the web with your current license

1. Sign in to Microsoft 365 using your @tha.ie business account.
2. Open Excel from the Microsoft 365 portal.
3. Upload your existing workbook.
4. Open and edit the file in Excel for the web.

Please ensure you are signing in with the correct business account and not a personal Microsoft account or another user account.

Option 2: Use the Excel desktop application

If you need to use the installed Excel application on Windows, the affected user will need a license that includes the desktop Office applications, such as:

• Microsoft 365 Business Standard
• Microsoft 365 Apps for business

You do not need to upgrade all users. Only the user who requires the desktop version of Excel would need a license that includes desktop applications.

I hope this information helps clarify the situation. If you have any further questions, please feel free to reach out again. I will be happy to assist you further.

Thank you for your understanding, and I wish you a wonderful day ahead.
