Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
As Madra mentioned (sorry, didn't see the above replies until I replied with me last post). It would be helpful to zip the contents so that the permissions and files are intact. This should resolve the issue. I don't think it should lock permissions or associate the permissions to the previous user if you do it that way, although I haven't had to share an app like this before, because you could usually just download again from the source. Again, hopefully Apple or Microsoft will sort their @&# out and we can get on with going the usual route for things.
