Microsoft: Exchange Server 2013 Reaches End of Support in April

Microsoft has reminded admins that Exchange Server 2013 is reaching its extended end-of-support (EOS) date in 60 days, on April 11, 2023. The announcement follows two other reminders issued in January and June when the company warned customers to upgrade or migrate their Exchange servers. The first version of Exchange Server 2013 was released in January 2013, and it reached its mainstream end date four years ago, in April 2018. Once the extended EOS date is reached, Microsoft will stop providing technical support and bug fixes for newly discovered issues that could impact the servers’ stability or usability. “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,” the Exchange Team said. “If you haven’t started your migration from Exchange Server 2013 to Exchange Online or Exchange Server 2019, get going now!”

Analyst Notes

It is recommended to upgrade any instances of Exchange 2013 to a newer version of Exchange as soon as possible. Exchange 2013 servers can also be migrated to Microsoft’s hosted Exchange Online email and calendaring solution, available as an Office 365 subscription or as a stand-alone service. Once mailboxes, public folders, and other data are migrated, admins can remove on-premises Exchange servers and Active Directory. Microsoft recently urged customers to keep their on-premises Exchange servers up to date to have them always ready for emergency security updates. On Tuesday, the company also released the February 2023 Exchange Server security updates, saying, “although we are not aware of any active exploits in the wild, our recommendation is to immediately install these updates to protect your environment.”
