This error can appear when you try to activate Office that's pre-installed on a new device but hasn't been updated to recognize Office 2019 product keys.
If you're using a new Office 2019 product key, here are two ways to fix this issue:
-
Update Office using the steps in Install Office updates and then try again
-
Install Office 2019 using the steps in Download and install or reinstall Office on a PC or Mac
This message can also appear when Microsoft 365 apps are pre-installed with your new device, but the Office products you own don't include the same apps. For example:
-
Outlook isn't included with Office Home & Student
-
Publisher isn't included with Office Home & Business
-
Access isn't included with Office Home & Student or Office Home & Business
If you want to use an Office app that's not included with the Office products you own, here are some options:
-
Buy the individual app from the Microsoft Store
-
Upgrade to Microsoft 365 or start a Microsoft 365 trial
