Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi user15052022,
Thanks for posting in the community.
According to your description, you want to activate and use Office 2016 Professional Plus on multiple devices. If so, if you only purchased one subscription (Office 2016 Professional Plus), you can’t activate and use Office 2016 Professional Plus on multiple devices. To activate Office on another device, you have to uninstall it on the original device.
For your reference:
Download and install or reinstall Office 2019, Office 2016, or Office 2013
If you still have any concerns, please feel free and come back to share with us.
Regards,
George
