Microsoft’s Exchange Server Subscription Edition: A Game Changer for Enterprise Email Hosting
If you’re still running on-premises Exchange 2016 or Exchange 2019 email servers, the time has come to embrace change. Microsoft has officially launched Exchange Server Subscription Edition (SE) to replace these standalone versions. This move entails a shift towards subscription-based licensing for both users and servers, accompanied by a price increase effective August 1.
To continue utilizing Exchange Server SE, enterprises must purchase the necessary Server licenses and Client Access Licenses (CALs) while also maintaining an active subscription. This means opting for cloud subscription licenses like Microsoft 365 E3 or E5 licenses or choosing Exchange Server SE licenses and CALs with Software Assurance (SA).
Microsoft’s decision to end support for Exchange Server 2016 and 2019 on October 14 underscores the urgency for organizations to transition to Exchange Server SE. While it’s possible to continue using the older versions post-end-of-life, it comes with inherent risks due to the lack of updates, technical assistance, bug fixes, and security patches from Microsoft.
Embracing a Modern Lifecycle Policy for Continuous Support
With Exchange SE, Microsoft is introducing a ‘modern lifecycle policy,’ ensuring continuous service and support without fixed end dates for releases. This evolution paves the way for ongoing product enhancements and simplifications, enabling customers to keep their configurations up to date.
The commitment to release Exchange SE Cumulative Updates (CUs) twice a year, along with necessary security or hotfix updates, guarantees that the product remains robust and secure. This transition aligns with Microsoft’s strategic shift towards a subscription-based model, aiming to provide customers with enhanced support and services in the long run.
Analysts highlight that while the price hikes accompanying Exchange Server SE may not be welcomed by all, the benefits of ongoing support and the flexibility to manage updates locally are compelling factors for organizations. This model offers a balance between cost considerations and the need for reliable email server solutions.
Navigating the Upgrade to Exchange SE
To smoothly transition to Exchange SE, organizations are advised to plan their upgrades meticulously. Microsoft recommends decommissioning Exchange 2016 or 2019 and upgrading to SE promptly. The upgrade process involves either deploying new servers for a legacy upgrade or opting for an “in-place” upgrade available for Exchange 2019.
During the upgrade process, some disruptions may occur, such as temporary mailbox pausing. However, organizations can mitigate these interruptions by scheduling upgrades during off-peak hours. It’s essential to note that the move to Exchange SE does not introduce significant changes, making the upgrade process relatively straightforward.
As the deadline for transitioning to Exchange SE approaches, organizations should focus on building a migration strategy, assessing infrastructure requirements, and aligning resources for a seamless transition. By engaging IT professionals with Exchange expertise and leveraging vendor support, enterprises can navigate the upgrade process efficiently and minimize any potential challenges.
In conclusion, Microsoft’s Exchange Server Subscription Edition marks a pivotal shift in how enterprises manage their email servers. By embracing this subscription-based model and leveraging continuous support and service enhancements, organizations can future-proof their email infrastructure and ensure seamless operations in the evolving digital landscape.
