Should you still buy Office 2021 for Mac?

Office 2021 for Mac reached the end of Microsoft support on 14 October 2026. The apps continue to work and your documents stay accessible, but Microsoft no longer releases updates or security fixes. Office 2021 for Mac makes sense only when you need to match an existing Office 2021 setup across several Macs.

For everyone else, Office 2024 Home & Business for Mac includes the same apps and is supported until 9 October 2029.
