Hi AndrewRomer,
Thank you for querying in this forum.
According to your description, it seems that you want to know how to manage user license and installations for Office professional plus 2019.
If my understanding is right, may I know if you are using volume licenses?
Generally, when you buy a subscription, you specify the number of licenses that you need, based on how many people you have in your organization. After you buy a subscription, you create accounts for people in your organization, and then
assign a license to each person. As your organizational needs change, you can buy more licenses to accommodate new people, or reassign licenses to other users when someone leaves your organization. Then those users can download the related Office products
according to the license you assigned.
And Microsoft Volume Licensing is a service offered by Microsoft for organizations that require multiple licenses, but not the software media, packaging and documentation supplied with the full packaged product (FPP). In software licensing,
a volume licensing is the practice of selling a license authorizing one computer program to be used on a large number of computers or by a large number of users.
If you purchased volume licenses, since our category focus on Microsoft 365 business products, and the question you mentioned is related to Office volume licensing, to make sure you get professional help, we’d suggest you go to
Volume Licensing Service Center to post a new thread, which is the specific channel to handle related questions.
If the scenario above is not consistent with yours, you can also post back and provide more details about your requirement and if you purchased volume licenses.
Your understanding and patience will be highly appreciated.
Best Regards,
Sukie
