Microsoft extends ESU period for Exchange Server and Skype, but at what cost? The company's decision has provided some relief to customers who were caught off guard by the initial expiration, but also raises important questions about its priorities and commitment to supporting legacy systems.
Microsoft is extending the extended security update (ESU) period for Exchange Server 2016/2019 and Skype for Business Server 2015/2019 from May 2026 to October 2026. The initial ESU period ended in April 2026, leaving some customers without access to security updates for their older systems. Customers will need to pay for the service and there are no guarantees that Microsoft will release any updates during this period. The extension raises questions about Microsoft's priorities and commitment to supporting older products. Some customers were previously caught off guard by the initial expiration and have been receiving temporary reprieve from the extended support period.
Microsoft, the software behemoth, has taken a significant step back from its previous stance on offering extended security updates (ESU) to older versions of Exchange Server and Skype for Business Server. In a recent announcement, the company revealed that it will be extending the ESU period for these products, despite having previously warned customers that this would not be done.
The situation begins with Microsoft's initial decision to offer six months of ESU for Exchange Server 2016/2019 and Skype for Business Server 2015/2019 after support for the products ended in October 2025. The company's announcement at the time included a stern warning: "This period will not be extended past April 2026 (you do not need to ask)." This statement was intended to convey that Microsoft would not offer any further extensions of the ESU period beyond April 2026.
However, as April 2026 drew near, some customers approached Microsoft and expressed their concerns about being unable to migrate to newer products in time. These customers were essentially caught off guard by the sudden expiration of the initial ESU period, leaving them without access to security updates for their older systems.
In response to these pleas from its customers, Microsoft has decided to extend the ESU period for both Exchange Server 2016/2019 and Skype for Business Server 2015/2019. The new period will run from May 2026 to October 2026, allowing customers to purchase additional security updates. However, it is essential to note that this extension comes with a price tag – customers must pay for the service, and there are no guarantees that Microsoft will release any updates during this period.
This decision by Microsoft has been met with mixed reactions from its customer base. On one hand, extending the ESU period provides some relief to businesses that were unable to migrate in time. It also acknowledges the concerns of those who may have felt pressured into purchasing newer products before they were ready.
On the other hand, this move can be seen as a double-edged sword for enterprise customers. While it offers temporary reprieve, it also reinforces the notion that some customers are willing to pay for security updates rather than migrating to newer systems. Moreover, this decision raises questions about Microsoft's priorities and its commitment to supporting older products.
Furthermore, Microsoft's admission that it prefers customers to finalize their migrations instead of relying on ESU periods can be seen as a tacit acknowledgment that some customers have been taking advantage of the extended support period. This may indicate that the company is beginning to reevaluate its strategy for providing ongoing support for legacy systems.
In conclusion, Microsoft's decision to extend the ESU period for Exchange Server 2016/2019 and Skype for Business Server 2015/2019 has provided some relief to customers who were caught off guard by the initial expiration. However, it also raises important questions about the company's priorities and its commitment to supporting older products.
Summary:
Microsoft has announced that it will extend the ESU period for Exchange Server 2016/2019 and Skype for Business Server 2015/2019 from May 2026 to October 2026, despite having previously warned customers that this would not be done. This move comes with a price tag and raises questions about Microsoft's priorities and its commitment to supporting older products.
