The Evolution of Skype: Embracing the Future with Skype for Business Server Subscription Edition
The ongoing discussion surrounding Skype’s relevance has been prevalent for some time. Although Skype as a standalone service is no longer operational, its professional counterpart, Skype for Business Server, continues to thrive. It is essential to distinguish between Skype and Skype for Business Server; the former served as a cloud-based communication platform that has since been replaced by Microsoft Teams, while the latter operates on-premises and remains unchallenged by Microsoft in terms of direct alternatives.
Understanding Skype for Business Server Subscription Edition
Microsoft has recently announced the general availability of Skype for Business Server Subscription Edition (SE).As the existing versions—Skype for Business Server 2015 and 2019—approach their end-of-life on the same date as Windows 10, SE provides a subscription model that ensures continued support. This aligns with Microsoft’s Modern Lifecycle Policy, under which software remains supported as long as users maintain up-to-date configurations.
Features and Upgrade Path
It’s essential to note that the Subscription Edition primarily commits Microsoft to license and service the evergreen product without providing significant feature enhancements. However, IT administrators should also be aware that Skype for Business Server SE can be installed as a cumulative update to the previous 2015 or 2019 versions. Microsoft has advised customers to transition to this latest edition promptly, as the numbered versions will cease receiving support after October 14, 2025.
In terms of configuration requirements, Skype for Business Server SE is largely identical to Skype for Business Server 2019. The primary changes lie in its branding, versioning, and updated licensing agreements.
The Future of Skype for Business
After the critical date of October 14, 2025, Skype for Business Server SE will stand as the sole supported version of this product. Even though both the subscription and numbered versions are currently operational concurrently, future updates will eventually phase out Skype for Business Server 2015 and 2019. However, Skype for Business Server SE will continue to receive cumulative updates, security patches, and modernized installation methods.
Why Skype for Business Still Matters
Despite the advancements offered by Microsoft Teams, the absence of on-premises installation options leaves a gap that Skype fills. Recognizing this, Microsoft has enabled Skype for Business Server to adhere to the Modern Lifecycle Policy, allowing continued monetization for businesses that choose to refrain from migrating to cloud solutions.
