Hello Fabio, the key is new and not already in circulation with others. MS Office 2019 is calculated for 1 user on 1 PC. O365 would be suitable for multiple users. Please note the correct licence model.
I hope this helps you.
Sincerely, Digimouse
Do I get a "fresh" key directly from Microsoft that I can be sure is not already in circulation and will cause problems when I activate it or something?
And do I understand correctly that this licence entitles me to install it on only one device, but that countless people (or user accounts) can then use the product on this device?
Specifically, I actually need an Office for 2 PCs on which two people work (with separate user accounts). Would I now have to buy this version twice (for each device) or even four times (for each user)?
Sorry for the long question, but I don't know what I'm looking for on the MS site.
