The Exchange Server 2016 & 2019 Deadline is Looming: Don’t Get Left Behind

The writing is on the wall: October 14, 2025, marks the official end of support for Exchange Server 2016 and older versions of 2019. This means no more critical security updates, leaving your organization vulnerable to cyberattacks.

The Danger of Delaying

Sticking with your outdated Exchange Server carries significant risks:

• Increased Security Breaches: Hackers actively target unsupported systems, putting your sensitive data at risk.
• Compliance Violations: Many industries have strict regulations requiring up-to-date security measures.
• Lost Productivity: You’ll miss out on the latest features and integrations that can boost team efficiency and collaboration.

Your Options: A Path Forward

You have a few choices:

• Migrate to Microsoft 365 Cloud:
  • Benefits: Enhanced security, seamless collaboration with other Microsoft 365 apps, increased productivity, reduced IT burden.
  • Consider this: If you’re looking for a modern, secure, and flexible email solution.
• Upgrade On-Premises for Exchange Server SE:
  • Consider this: If you prefer an on-premises solution, upgrade to the latest Exchange 2019 to prepare for the upcoming Exchange Server SE (Subscription Edition).
