What to know before you buy
Microsoft ended support for Office 2021 on October 13, 2026. The software and your license keep working, but there are no more security updates. Some organizational features, such as Information Rights Management and Data Loss Prevention, depend on services that your company provides and are not part of the standalone license. If you want a version that is still supported, look at Office 2024 Professional Plus, supported until October 2029.
