I recently purchased Microsoft Office 365 to use with Parallels/Windows 7 Pro. Although I have this installed on the VM and I can open these Microsoft Office applications I find that I must sign in every time I open the app (sign in through the Word/Excel/etc.). Additionally, the app requires that I setup file associations each and very time I open a Microsoft Office app. And, furthermore, when I sign into the account.microsoft.com area - I do not see the VM Parallels/Windows7Pro as a "Device" (as I do with a dedicated windows machine). So, there's some kind of problem associated with using Microsoft Office 365 with a virtual machine - it would seem. Anyway, the first order question is this: Can I use Microsoft Office 365 with Parallels/Windows7Pro?
