Microsoft 365 (Formerly Microsoft Office): A Complete Guide

What you need to know about the world’s most popular apps package

Microsoft Office was a suite of office-related programs. Each application serves a different purpose and provides a unique service to its users. For example, Microsoft Word is used to create documents. Microsoft PowerPoint is used to create slideshow presentations, and Microsoft Outlook is a program used to manage email and calendars. There are a few more.

What Is Microsoft 365?

Microsoft 365 Logo

Since 1988, various versions of the Office suite have been available, including but not limited to Office Professional, Office Professional Plus, Office Home and Student, and various Office 2016 collections.

However, most people still refer to any version of the Office suite as Microsoft Office, making distinguishing between editions difficult.

Microsoft Office 2019 is the most recent version of Microsoft Office, though Microsoft prefers users to use the web-based Microsoft 365.

What distinguishes Microsoft 365 from previous editions of MS Office is that it integrates all aspects of the apps with the cloud.

It is also a subscription service, which means users pay a monthly or yearly fee, with upgrades to newer versions included.

Previous versions of MS Office, including Office 2016, did not include all of the cloud features available in Microsoft 365 and were not subscription-based. Office 2016 was a one-time purchase, as were previous editions and Office 2019 or Office 2021.

Who Uses Microsoft Office and Why?

Users typically purchase a Microsoft Office suite when they discover that the apps included with their operating system are insufficient to meet their needs.

It would be nearly impossible, for example, to write a book using only Microsoft WordPad, the free word-processing app included with all editions of Windows. However, writing a book is possible with Microsoft Word, which has many more features.

Microsoft Office business suite apps include those you can use to manage large user databases, perform advanced spreadsheet calculations, and create powerful and exciting slideshow presentations, complete with music and video.

Businesses also use MS Office to complete different business requirements. It has become the de facto standard for large corporations.

Microsoft claims over a billion people use their MS Office products. The Office software suite is used all over the world.

What Devices Support Microsoft Office?

Most devices, including laptops, desktops, tablets, and smartphones, allow you to access everything Microsoft Office offers.

You can use the Microsoft Office Online suite of applications if you don’t have a computer or if the one you have doesn’t support a full version of Office.

There are also Microsoft Office apps for the iPhone and iPad, which you can download from the App StoreGoogle Play has a selection of Android apps.
