I installed MS Office 2010 on my Manjaro (Cinnemon if it matters) and the installation via playonlinux worked just fine and the programm is working as expected ...
BUT: I always get the activate via Internet Dialog and if i confirm the Activation attemt it doesnt work with an error message please verify internet connection. I also found and tried the aditional program Office 2010 activation available via playonlinux but either i used the wrong IP/Port in this programm or it didnt work. Btw. The second way to activate (via Phone) was disabled years ago because Office 2010 is to old

I can provide you some Screenshot with the Dialogs i Mentioned but they are all in German as I`m from Germany and installed the German Office 2010
