Microsoft Office 2021 is a suite of productivity applications designed for personal and professional use. It includes popular programs like Word, Excel, PowerPoint, and Outlook, which help users create documents, analyze data, make presentations, and manage emails. This version is available for both Windows and Mac operating systems. Unlike the subscription-based Microsoft 365, Office 2021 is a one-time purchase, allowing users to own the software without ongoing fees. It features updated tools and improved collaboration options, making it easier for teams to work together, whether in the office or remotely.
