Right this is the most stupid problem I have ever had, and Microsoft support were just impossible to deal with.

I have installed Office 365 on 3 PC's, 2 are running Windows 8, 1 is running Windows 7.

I don't like being connected to things all the time to be honest, yeah the internet thats ok, but I dont feel my programs need to be, I just don't feel comfortable with it, so in Word I went to Account and Sign Out and it amazingly just says "We can't remove Windows accounts". Great so I cannot sign out at all.

Not even Microsoft know whats going on, does anyone know how to sign out?

Further to that the Windows 7 computer is not signed in so no worries there, I can only assume all this has to do with the Microsoft Account on the Windows 8 machines but even so this is a bit silly.
