Microsoft has officially announced it will terminate support for Office 2021 on Oct 13, 2026. While users will still be able to operate the software normally, the tech giant will no longer provide security patches, bug fixes or technical assistance. According to a statement on Microsoft's official website, although the program will remain functional, users could face severe security risks from unpatched vulnerabilities that emerge after the end-of-support deadline.

Official customer support channels, including chat assistance, will be discontinued for this version.

Users seeking continuous updates, new features, bug fixes and robust security defences are advised to transition to Microsoft 365, the company's cloud-based subscription service.

Alternatively, consumers and enterprise clients looking to avoid recurring subscription fees can opt for Office 2024. This version is available as a one-time, perpetual purchase, making it an ideal choice for businesses and individuals preferring traditional software licensing.

The announcement reflects Microsoft’s broader strategy of encouraging users to migrate towards cloud-connected and subscription-based productivity services.
