​​​​​​​Office suites for enterprise, business, education, and government 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). Starting with the 2021 release, the commercial version of the Office suite has been called Office Long-Term Servicing Channel, or “Office LTSC.”

General information

Although security updates and quality updates to Office suites for commercial customers are made available via the internet, they can be hosted on-premises for disconnected networks. Office suites for commercial customers do not receive feature updates after release. If you want to get new features on an ongoing basis, consider moving to an Office 365 or Microsoft 365 plan.

Microsoft 365 is designed to work with the latest browsers and versions of Office. If you use older browsers or 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.

  • Microsoft won’t provide code fixes to resolve non-security related problems.
