The Microsoft licensing changed in fall of 2020. Most faculty and staff have an A3 license with full access to desktop office apps and noticed no change. Emeritus, retirees, students, extra help and some other classifications have an A1 license which restricts their access to desktop apps, but still allows access to the online version of the app.
Emeritus faculty to not receive an A3 license by default. If they have an active appointment (such as academic hourly) then the employee will have has access to Webstore and can purchase the license upgrade using a departmental FOP. It is up to the department to determine if they will allow the Emeritus employee to buy the software with department funds.
