Microsoft Office LTSC 2021 generally available

Effective October 8, 2021, Microsoft Office LTSC 2021, the next perpetual license of Office is available. LTSC stands for Long Term Servicing Channel:

  • Office LTSC Professional Plus 2021
  • Office LTSC Standard 2021
  • Office LTSC Standard for Mac 2021
  • Project * Professional 2021
  • Project * Standard 2021
  • Visio LTSC Professional 2021
  • Visio LTSC Standard 2021

* Microsoft omits “LTSC” with Project 2021

Office LTSC offers five years of support and is built for specific situations, such as regulated devices that cannot accept feature updates for years at a time, process control devices on the manufacturing floor that are not connected to the internet, and specialty systems that must stay locked in time.

As installation technology Office LTSC uses Click-to-Run instead of Windows Installer (MSI) as with Office 2016 or earlier. Activation remains the same by using Key Management Service (KMS) or Multi Activation Key (MAK).

Office LTSC 2021 is separate from the Office that’s available through Microsoft 365 or Office 365 plans. If you have deployed Microsoft 365 Apps for enterprise (previously named Office 365 ProPlus), you don’t need Office LTSC 2021. You already have all the features that are included in Office LTSC 2021, along with many more features that aren’t available in Office LTSC 2021.

Office LTSC 2021 won’t receive any new features after its release. If you want to get new Office features on an on-going basis, you should consider moving to a Microsoft 365 (or Office 365) plan that includes Microsoft 365 apps for enterprise, i.e. Microsoft 365 E3 or E5.
