Commercial Preview of Microsoft Office Long Term Servicing Channel (LTSC) is Now Available

Published 04-22-2021 09:14 AM 11.4K Views

Today we’re pleased to announce the commercial preview of Microsoft Office Long Term Servicing Channel (LTSC) for Windows and Office 2021 for Mac. The next perpetual version of Office for commercial customers is built specifically for organizations running regulated devices that cannot accept feature updates for years at a time, process control devices that are not connected to the internet in manufacturing facilities, and specialty systems that must stay locked in time and require a long-term servicing channel. Office LTSC will provide the familiar productivity tools you have experienced with Office 2019, now with faster performance and expanded accessibility. You can preview Office LTSC and Office 2021 for Mac starting today. 


Office LTSC will include features from past Office releases as well as a subset of new features already available in Microsoft 365 Apps for enterprise. As we announced in February, Office LTSC, like Windows 10 LTSC, will be supported for five years and continue being governed by the Fixed Lifecycle Policy. To learn more about other changes for Office LTSC read our February announcement. 


Office LTSC will be deployed using Click-to-Run exclusively, just like Office 2019, so IT admins can take advantage of modern deployment technology to help reduce costs. Office 2021 for Mac will use the standard Apple Package format (pkg) - the same technology that we have used for previous perpetual releases, including Office 2019 for Mac and Office 2016 for Mac. To understand additional system requirements for Office LTSC and Office 2021 for Mac, read the FAQ. 


Microsoft 365 Apps continues to deliver the most productive and most secure Office experience, offering the lowest Total Cost of Ownership (TCO) for deployment and management. In another recent announcement, we shared how Microsoft 365 Apps can also be used in organizations with employees going offline for longer periods of time or using shared devices or workstations. However, Office LTSC will be a valuable upgrade for customers who need to keep their Office Apps on-premises.  


This is the first in a series of preview announcements for the on-premises wave, and in the coming months we’ll also announce commercial previews for SharePoint and Project Server. For instructions on how to install the Office LTSC and Office 2021 for Mac preview, go here

Hi @Microsoft_365_Team thanks for the announcement.


For the matter of consistency will you name it Office 2022 such as Windows Server and Exchange?


Will the new Office be available as MSIX installation? 


Could you share the Office and Server compatibility and support matrix as you did as PDF for earlier versions? 



Hello @K_Wester-Ebbinghaus,


Thanks for your questions! We're happy to answer them. 


1) The commercial perpetual version of Office will be named "Office LTSC" for Windows and "Office 2021 for Mac" for Mac.


2) MSIX will not be supported for Office LTSC. Click-to-Run will be used for Windows and standard Apple Package format for Mac.


3) The matrix will be available at GA in the second half of 2021.


Let us know if you have any other questions about this announcement.

Thank you for your brief and helpful replies. Looking forward to #3. It would be great if MS Partner could get this ahead of time so it would make it easier to plan licensing for Office and Server, also projects planned for 2021.

Does this version enable turning off the sandbox features? 


I have 20 year old vba code I use to run my classrooms.  It runs unattended on Windows just fine but porting to the Mac hasn't worked due to the sandbox. 

Occasional Visitor

Is OneDrive and/or OneDrive for Business part of the this Preview?

And will it be Part in the Final Release?



Thanks for your question!


Office for Mac continues to be sandboxed. Apple's sandbox is a security mechanism that is the standard for Mac applications. We have an article here written for Office 2016 for Mac and VBA, when sandboxing was introduced. This article would still apply to Office 2019 and Office 2021 for Mac: Office for Mac for Visual Basic for Applications (VBA) | Microsoft Docs.

@patgerber OneDrive aswell as their admx files are best available as seperate download. They are easy to deploy. 

If you don't use a software deployment you can use winget or WinPGK


I wouldn't distribute it via Office LTSC or 365 for Business apps. 


One reason is the recommendation in the to switch to /allusers installation.


Secondly a 64bit OneDrive is on the way (has some functionality regression according to Hans Brender (MVP), not sure if these still exist)

Here are all downloads and release notes. 


Third OneDrive Updates don't align with Office Update cadence.
