Office 2021

Office 2021 is a version of Microsoft Office released on 5 October 2021 along with Windows 11. Unlike Office 2019, this version is supported for only five years instead of seven as the extended support period has been entirely eliminated. Office 2021 is the first version of Microsoft Office since Office 95 to not have an extended support period.

In October 2022, Microsoft announced that Office 2021 would be the last version of Microsoft Office as its components will eventually be rebranded as Microsoft 365 in 2023, while Microsoft previously replaced Internet Explorer with Microsoft Edge in Windows 10 and later.

Support for Office 2021 will end on 13 October 2026.
