Microsoft is rolling out the Office 2021 with Dark Mode

For personal or small business use Microsoft releases Office 2021 and Office 2021 LTSC. The company has launched a commercial version of Long Term Servicing Channel (LTSC) which will be available later this year.

Microsoft Office LTSC's commercial preview will be working in April. Here, it should be noted that Office 2021 replaces Office 2019.


It is designed for people who are unwilling to accept the Microsoft 365 variants with cloud power. Microsoft released LTSC with the support of dark mode across multiple apps and improved performance across Word, Excel, Outlook, and PowerPoint.

Microsoft is not yet complete with the feature information and the Office 2021 changes, but it has yet another thing revealed that some valuable things such as support for the dark mode, the available upgrades and features such as Dynamic Arrays and XLOOKUP Excel come from the Office LTSC (Long-Term Servicing Channel).


In a blog post, Microsoft said:

"When we log with our screens for long hours, reduced eye strain and light sensitivity has become increasingly important. We have therefore extended the Black Office theme to include your canvas for your document. This is a feature many officials have long been asking for and we are excited to do so."

Users should click on File >> Account >> Office Theme >> Black to access the feature.
