Office LTSC 2021 vs Office 2021

The main difference between Microsoft Office 2021 and LTSC 2021 is their target audience and the features they offer.

Office 2021 is primarily used by individual customers and small businesses. Office 2021 LTCS is primarily intended for government and commercial use.

The biggest difference between them is Visual Refresh. This feature includes a new Office theme and Quick Access Toolbar that match your Windows theme. This is only available in Office 2021.

Also, the ability to co-author documents is not included in Office LTSC 2021. This means you also can’t see who is working on the same document as you.

Office LTSC 2021 is separate from Office offered through Microsoft 365 plans. For example, if you’ve deployed Microsoft 365 Apps for enterprise to users in your organization, you don’t need Office LTSC 2021. Microsoft 365 Apps for Enterprise already has all the features included in Office LTSC 2021.
