Office LTSC 2021 is the most recent on-premises version of Microsoft's productivity software that's available to organizations through a volume licensing agreement and is available for enterprise admins to download and deploy to the users in their organization.  See Overview of Office LTSC 2021 and Microsoft 365 and Office Resources for more information.

How to buy

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.

Volume Licensing

Microsoft offers volume licensing programs to help reduce administrative overhead and software management costs for your organization, while enabling product licensing on an ongoing basis at considerable discounts. The various licensing options enable you to choose the program that works best for your management and operational needs.   Please see Office applications in the Product Terms site for program availability, Overview of volume activation of Office, or contact your local reseller for assistance.
