Office 2021 Standard for Mac LTSC

Office LTSC 2021 suites for business are a one-time purchase that may be acquired for more than five computers through volume licensing. Office as a one-time purchase does not include any of the services included in Microsoft 365 (for example, Exchange Online, SharePoint Online).

Microsoft 365 is designed to work with the latest browsers and versions of Office. If you use older browsers and versions of Office that are not in mainstream support: 

• Microsoft won’t deliberately prevent you from connecting to the service, but the quality of your Microsoft 365 experience may diminish over time.
• Office LTSC 2021 connections to Microsoft 365 services will be supported until October 2026.
• Microsoft won’t provide code fixes to resolve non-security-related problems.
• Office LTSC 2021 is supported under the Fixed Lifecycle Policy.
