I recently bought a new 5K iMac and am setting up apps. I was limping along on Microsoft Office 2008 and decided to buy Office 2016 for the new machine. I'm immediately turned off by the fact that I had to create a Microsoft account to install the software (using a key card bought from Amazon). Furthermore, Office keeps trying to get me to use OneDrive online storage. I don't need any of my documents online, I have no need for them there and don't like it from a security standpoint. My question is: can I safely DELETE my Microsoft account now that I have the apps downloaded and installed? Or is the Microsoft account required to 1) keep using the apps and 2) keep receiving updates? I do not want anything to do with my online Microsoft account, I just want to use Word/Excel and save files locally.
