Office 2021 arrives in two versions: one for commercial users called Office LTSC (which stands for Long Term Servicing Channel), and one for personal use. The company previously emphasized that while its main focus remains on its Microsoft 365 subscription offering, it will release the one-time purchase Office 2021 for those who aren't yet ready to move to the cloud. Microsoft's new, flat-price version of its Office productivity software started rolling out Oct. The 2021 version of Microsoft Office won't require a subscription.
