Microsoft’s Exchange Server: The Final Countdown – Upgrade or Face the Chaos!
Exchange 2016 and 2019 are approaching their end-of-support date next month. Microsoft recommends migrating to Exchange Online or upgrading to Exchange Server Subscription Edition. If you continue using these outdated servers after October 14, 2025, you’re essentially inviting security breaches over for tea and biscuits. Time to upgrade those servers!
Hot Take:
Microsoft is basically telling admins, “Hey, remember that old jalopy you’ve been driving? Yeah, it’s time to upgrade before you end up stranded on the side of the digital highway.” Consider this the gentle nudge—or perhaps a firm shove—you needed to stop living in the past and join the 21st century. After all, no one wants to be that person with the email system equivalent of a flip phone.
Key Points:
- Exchange 2016’s mainstream support ended in October 2020; Exchange 2019’s in January 2024.
- Microsoft will stop technical support and security fixes for these versions after October 14, 2025.
- Admins are advised to migrate to Exchange Online or upgrade to Exchange Server SE.
- In-place upgrades are available from Exchange 2019 to Exchange SE.
- Migration guidance is available on Microsoft’s documentation site.
