What you need to know

  • Microsoft Office Long Term Servicing Channel for Windows and Office 2021 for Mac are available in public preview.
  • These versions of Office don't require a subscription, instead of being available as a one-time purchase.
  • Microsoft Teams will ship with these versions of Office rather than Skype for Business.

Office LTSC has all of the features from its predecessor plus a "subset of new features already available in Microsoft 365 Apps for enterprise," according to a Microsoft Tech Community Post. The post does not share a list of the new features for Office LTSC. Previously, Microsoft shared that "Dynamic Arrays and XLOOKUP in Excel, dark mode support across multiple apps, and performance improvements across Word, Excel, Outlook, and PowerPoint," will be in the new version of Office LTSC.

Like Windows 10 LTSC, Office LTSC will be supported for five years and be governed by the Fixed Lifecycle Policy.

Unlike previous versions of Office that shipped with Skype for Business, the new versions of Office will ship with Microsoft Teams. People can still install the Skype for Business client app through Microsoft Download Center.

Microsoft shares that today's announcement is just the first in a series of preview announcements for the on-premises wave. Over the coming months, the company will announce commercial previews for SharePoint and Project Server.
