Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi Aaron,
What kind of license did you purchase? Here's how to activate your Office apps:
ACTIVATE MICROSOFT OFFICE
Stand-alone perpetual license:
Activate Office for Mac - Microsoft Support
-or-
MS 365 subscriber:
Activate Office - Microsoft Support
However, the message suggests that the license type you have allows use of only the on-line applications, not the desktop applications, which will prevent you from being able to activate the desktop applications.
