Microsoft Office suite was rolled out in 1990. In its early years, it included only three primary apps: PowerPoint, Word, and Excel. But over the years, the number of applications in the MS Office Suite increased from three to many more. Now every app of Office Suite comes with professional features like collaborating tools, spell checker, grammar checker, digital notebook, and planner. You can get access to the Microsoft Office setup from www.office.com/setup. These professional features, as mentioned above, also work on the MS Office suite apps for mobile phones.
