Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi,
I wish I had a better answer, but Unfortunately, once an Office/Microsoft 365 product key has been redeemed, it becomes associated with the Microsoft account used during redemption. The key cannot normally be redeemed again or transferred to another Microsoft account.
The ideal next step is to contact Microsoft Support and provide the original product key and proof of purchase/business ownership, which may result in a license replacement.
Please contact Microsoft Support for further assistance.
Exact steps to reach support:
- Please go to the https://support.microsoft.com/en-us/home/contact page.
- Click Microsoft Office / Windows depending on the issue.
- Click Get Home Support.
- Type "Billing" and press Enter.
- Please click on the "Contact support" button at the bottom.
- Select the Category for support based on your requirements.
I hope this information helps. If you have any more questions, don't hesitate to reach out.
