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.
