Microsoft is continuing its legacy product support strategy by announcing that it has officially entered the second phase of Extended Security Updates (ESU) for Skype for Business and Exchange Server. This move is a strong signal that the transition to more modern systems is becoming increasingly urgent.
Microsoft’s decision to initiate the second phase of ESU for Skype for Business and Exchange Server demonstrates that even though these products have reached the end of their mainstream support period, user demand for security updates remains high.
For many organizations, Microsoft’s initiation of the second phase of ESU for Skype for Business and Exchange Server serves as an important reminder to immediately plan their migration to newer platforms before security risks escalate.
What Is ESU and Why Is It Important?
Extended Security Update (ESU) is a paid program from Microsoft that provides additional security updates for products that have passed their official support period.
With ESU, companies can still receive protection from cyberthreats, even if their systems are considered outdated. However, this program is temporary and not a long-term solution.
Second Phase: Higher Costs, Greater Risks
Entering the second phase, ESU costs typically increase compared to the previous phase. This is Microsoft’s strategy to encourage users to quickly switch to newer services like Microsoft 365 or Exchange Online.
Furthermore, the longer they use an outdated system, the greater the security risks they face, especially if not all vulnerabilities can be closed with limited updates.
Skype for Business and Exchange: Is It Time to Migrate?
Skype for Business has long been eclipsed by Microsoft Teams, which offers more comprehensive and integrated features. Meanwhile, Exchange Server is being abandoned by many organizations as they transition to cloud-based solutions.
With the start of the second phase of the ESU, Microsoft is indirectly signaling that the lifespan of these two products is nearing the end.
For companies, migration is not easy. It requires money, time, and system and human resource adjustments. However, delaying migration is also unwise, given the ever-evolving security threats.
Organizations need to consider long-term strategies to avoid continuing to rely on legacy systems that are increasingly expensive and risky.
Conclusion: Time is Short
Microsoft’s decision to start the second phase of the ESU for Skype for Business and Exchange Server is a clear signal that the era of legacy products is coming to an end. ESU only provides additional time, not a permanent solution.
For users, this is the opportunity to adapt quickly and switch to more modern, secure, and efficient technology before it’s too late.
