I am trying tom use Office products on a new device and I am being told that they can't verify my product key from my old laptop/software. I am certain that I am using the proper key and am not translating any of the characters incorrectly.

Hi, I'm John! I will help you with this.

First, can you tell me which version of Office your product key is for (for example, Office 2016, Office 2019, or Office 2021)? Some older keys may not work if they’re linked to a Microsoft account or if they were tied to a specific device or OEM license.

If you haven’t already, please try signing in at https://account.microsoft.com/services using the Microsoft account that was originally used to activate Office on your old laptop. If the license appears there, you can reinstall it directly from that page without needing to enter the key again.


If the issue persists, please provide more details I'm here to help you further.

Regards,

John J.D.
