Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Dear @SANTHANARAJ MAGIMAI RAJ,
Thank you for posting your question in the Microsoft Q&A forum.
Is there a problem with your Office app?
Are you using a work/school account or a personal account?
Does an error message pop up? (e.g., 'Something went wrong' or 'Unlicensed Product'). Please help me take a screenshot.
Is Office on the web working fine for you right now?
Based on that information, I will be able to suggest the most appropriate next step for you.
Looking forward to your response!
