Microsoft Office 2021 is the latest version of the Office productivity suite, released in October 2021. It includes essential applications like Word, Excel, PowerPoint, Outlook, and Access. Office 2021 builds on features introduced in Office 2019, offering improvements in collaboration, performance, and usability. New features include improved Excel functions, better PowerPoint transitions, and enhanced tools for inking and drawing. It also supports collaboration through co-authoring in real-time, although it does not require a subscription to use. Office 2021 is designed for users who prefer a one-time purchase over a subscription-based model like Microsoft 365.
