Microsoft Exchange & Skype Servers Go Subscription-Only

Microsoft has officially launched subscription-only versions of its on-premises Exchange Server and Skype for Business Server, thereby ending the era of year-numbered releases and perpetual licences.

A Long-Anticipated Transition Becomes Reality

After months of preparation and close calls with support deadlines, Microsoft has made its Subscription Edition (SE) versions of Exchange Server and Skype for Business Server generally available. These editions replace the traditional 2016 and 2019 versions, which are set to reach the end of extended support on 14 October 2025.
