Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi Fiona Cameron,
Thank you for reaching out to Microsoft Q&A Forum, and I completely understand how confusing this situation is, especially since it happened on your first day at a new job.
Based on how Microsoft Office activation works, once a product key is redeemed, it automatically becomes permanently tied to the first Microsoft account that was signed in at the time of activation. According to Microsoft’s documentation, trying to activate again with a different email will show a message that a different account was used for the product key, and the key cannot be moved afterward.
This means your Office Home & Business 2024 key is now linked to your personal Outlook email, not your work email, even though it happened by accident.
Here are the only workable options:
- Use Office on this laptop by signing in with the personal email that owns the license This is the fastest way to get Office working. You simply need to open Word or Excel, sign out of your work account inside the app, and sign in using the personal Outlook email that the key was attached to.
- Contact Microsoft Support to see if they can review the activation: Microsoft Support is the only team with access to verify activation history and advise if anything can be done. You can reach them here: https://support.microsoft.com/contactus → Describe your issue → Press Enter → Scroll down and choose Contact Support.
They will be able to check the activation history and provide guidance on next steps. Hopefully my response gives you some useful directions toward fixing this.
