Microsoft has reminded customers that the Exchange Server 2013 mail and calendaring platform will reach its extended end-of-support date roughly nine months from now, on April 11, 2021.
Released in January 2013, Exchange Server 2013 entered its ninth year of service and has already reached the mainstream end date more than four years ago, on April 10, 2018.
Admins will also not be provided with security fixes addressing vulnerabilities impacting servers running Exchange Server 2013.
“Exchange Server 2013 will continue to run after this date, of course; however, due to the risks listed above, we strongly recommend that you migrate from Exchange Server 2013 as soon as possible,” said Scott Schnoll, Product Marketing Manager for Microsoft Exchange.
“If you haven’t already begun your migration from Exchange Server 2013 to Exchange Online or Exchange Server 2019, now’s the time to start planning.”
Customers who want to keep their servers running software still receiving bug fixes and security updates for newly discovered flaws are advised to upgrade on-premises servers to Exchange Server 2019.
