Problem Description: Showing Product Deactivated Despite

Hello Support Team, I am facing an issue with Microsoft Excel. Even though my Microsoft 365 license is active and properly assigned, Excel is showing the message: “Product Deactivated – Most of the features of Excel have been disabled.” I am able to send and receive emails using Outlook 365 without any problem, which confirms that my license is valid. However, Excel remains deactivated. I have already tried restarting the application and signing in again, but the issue still persists. Kindly check my account and advise how this issue can be resolved as soon as possible. Thank you for your support. [Moderator note: personal info removed]
