Microsoft is killing Office 2021 in October to push you onto Microsoft 365, how to fight back

Microsoft is once again ringing the death knell of Office 2021, this time with an End of Support for Office 2021 reminder on its Microsoft Support document.

In an updated support document spotted by Windows Latest, Microsoft reiterates that it will officially end support for Office 2021 on October 13, 2026. As of now, the company seems steadfast on the EoS date and doesn’t appear to be offering any last-minute reprieves or concessions for die-hard Office 2021 fans.

After October 13, 2026, you will be operating Microsoft’s 2021 Office Suite without patches, fixes, or official security support from the company.

While Microsoft may be eager to push more users toward its subscription-based productivity offerings, many users of Office 2021 view this solution as the last ‘buy once, own forever,’ stable, predictable version of Office that doesn’t bog down productivity with a bunch of beta AI tools as add-on services.
