This chapter explores Microsoft 365 Apps, Microsoft's flagship productivity suite available with most Microsoft 365 subscriptions. It includes applications like Outlook, PowerPoint, Word, Excel, OneNote, Publisher, OneDrive for Business, Teams, Access, and Sway (web version only). The suite is included in the SaaS monthly cost, with no separate purchase required. Users can install the software on up to five devices, including PCs, Macs, tablets, and mobile platforms. The product key limits installations to five, with each installation tracked by Microsoft 365. Companies may choose between Office 365 Apps or traditional Office 2019 licenses based on their agreement. Users can download and install Office 365 Apps via the Microsoft 365 portal. They can also use Office Online versions of Outlook, PowerPoint, Word, Excel, and OneNote in modern browsers, though some tasks may not be possible in the online versions.
