Office 365 Pro Plus is just like any other Office version and it contains all the basic features that you will find in other Office versions. It is not a web based version and works locally on your computer. It means you don’t need to be connected to the internet for using its features. Though it has many similarities to the other Office versions but still their are differences like Office 365 Pro Plus need to renew license every month and if you will not renew its license it will go into the reduced functionality mode in which you can open and view your old files with less features. Office 2013 Professional Plus is another great alternative.
