Exchange Server 2019 has less than six months of support left in the tank
Microsoft has put administrators on notice that Exchange Server 2019 is nearing the end of its support lifecycle. As of October 14, 2025, both Exchange Server 2016 and 2019 will be unsupported, and the follow-up, Exchange Server SE, won’t hit the shelves until July 2025. This leaves little time for proper migration prep.
Key Points
- Support for Exchange Server 2019 ends on October 14, 2025, leaving less than six months of assistance for users.
- Exchange Server SE is set to be released in July 2025, giving administrators a narrow window for migration.
- Microsoft is encouraging users to switch to Exchange Online, highlighting the risks of not upgrading.
- Prices of on-premises server products will increase by 10% starting July 2025, adding financial pressure for users.
- Many existing setups rely on Slack; system admins must thoroughly test any upgrades before implementation.
