Microsoft made a public preview of Office LTSC available in late April this year. Office LTSC will get five years of support total, as will Office 2021. Microsoft watcher Mary Jo Foley's blog covers the products, people and strategies that make Microsoft tick. They've also said previously that the pricing of the Office 2021 SKU won't change from the current Office perpetual SKU pricing. So far, Microsoft officials have shared that Office 2021 will be limited to use on a single PC or Mac. Officials said more details about Office 2021 would be available at that time. Microsoft will be launching Windows 11 on October 5.

Microsoft's other non-subscription, next-generation Office release, known as Office 2021, which Microsoft is positioning as its consumer-focused, non-subscription release, will be available on October 5, officials said today. Office LTSC is available globally to all volume-licensed customers starting today.

Office LTSC, or Long Term Servicing Channel, offers a subset of the features that are included in Microsoft 365/Office 365 Office releases and is meant for specific, regulated scenarios. Microsoft is making one of its two non-subscription-based, next-generation Office releases - Office LTSC - generally available on September 16.
