Microsoft 365 is a subscription-based service and, to try and experience the functionality of each product and service, a user must have an appropriate license. It does not matter whether a user has a trial license, or they have a “regular” or paid license – as long as they have a license assigned, they can enjoy the proper product.

More than a decade ago, Microsoft introduced Office 365, a software as a service (SaaS) offering, as a natural evolution from the very popular business productivity suite. The suite, or the bundle, consisted of core productivity desktop-based applications such as Outlook, Word, Excel, PowerPoint, OneNote, and Access, including server-based services such as SharePoint, Exchange, and Skype for Business.

It became obvious that productivity encompasses and needs more than just productivity tools. That led to a logical move by Microsoft to include more essential products and services and bring together Windows and Enterprise Mobility + Security (EM+S) to form Microsoft 365.

Microsoft 365 is a name for Microsoft’s cloud-based service, that is, a collection of cloud-based services with common denominators including enhanced user productivity, efficient collaboration, and communication, while keeping data and devices secure wherever they are, whether that be in the office, at home, or on the go.

One of the main benefits of Microsoft 365 is that it allows users to access their files and applications from anywhere on any device. This is made possible through the integration of cloud-based services such as OneDrive, which allows users to store and share files online. This means that users can access their files from a desktop computer, laptop, tablet, or smartphone, as long as they have an internet connection.

Another benefit of Microsoft 365 is the ability to collaborate and communicate with others in real-time. Applications such as SharePoint and Teams allow users to share and co-author documents, as well as participate in virtual meetings and chat with their colleagues. This makes it easy for teams to work together, regardless of their physical location.

In addition to the productivity and collaboration features, Microsoft 365 also includes security and compliance tools to help protect users’ data and ensure compliance with regulatory requirements. For example, it uses machine learning and behavioral analysis to detect and block malicious emails, links, and files, and can also help to identify and respond to security threats in near real-time. Among many features that Microsoft 365 offers is Data Loss Prevention (DLP), which helps to prevent sensitive data from being shared or leaked. DLP is just one of the numerous Microsoft 365 security features; we will take a closer look and learn more about them later in the book.

In terms of compliance, Microsoft 365 includes several features to help organizations meet regulatory requirements. For example, it includes eDiscovery, which allows administrators to search for and export data from email, SharePoint, and Teams to comply with legal and regulatory requests. Additionally, it also includes retention and archiving capabilities, which allow organizations to retain and archive data for compliance purposes.

In general, Microsoft 365 is a comprehensive solution for businesses and individuals looking to increase their productivity, collaboration, and communication while also ensuring the security of their data. With its range of applications and services, it provides users with everything they need to work effectively, whether they are in the office or working remotely.

As a subscription-based service, Microsoft 365 offers subscription plans and bundles tailored for personal use, small businesses, enterprises, schools, educational and governmental users, and more.

While classic Office applications such as Word, Excel, Outlook, and PowerPoint are available as a one-time purchase via Office Home & Business 2021 or Office Home & Student 2021, these do not include some popular capabilities and products such as cloud storage or Microsoft Teams.
