Microsoft to End Support for Exchange Server 2013 in April

Cloud Computing

Microsoft is reminding customers that it’s ending extended support for Exchange Server 2013. After April 11, 2023, the older version of Exchange Server will no longer receive any new security patches, technical support, time zone updates, and bug fixes.

Microsoft launched Exchange Server 2013 back in January 2013. The company ended its mainstream support four years ago, but April 11 marks the end of extended security updates for Exchange Server 2013. Microsoft has warned that the older version will continue to run, but it would be vulnerable to security risks.

“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. If you haven’t started your migration from Exchange Server 2013 to Exchange Online or Exchange Server 2019, get going now,” the Exchange team explained.

Plan your migrations to Exchange Server 2019 or Exchange Online

Microsoft plans to release the next version of Exchange Server in 2025. In the meantime, the company strongly recommends customers to migrate to Exchange Server 2019 or Exchange Online. Exchange Server 2019 includes several security capabilities, data loss prevention features, and improvements to compliance. It’s suitable for organizations that want to maintain their systems in on-premises environments.

Alternatively, Microsoft says that organizations can also choose to migrate to Exchange Online. It offers new tools such as Viva Insights and focused inbox, larger mailboxes, as well as improved antimalware and spam protection. Microsoft has also published a guide to help IT admins plan migrations to Exchange Online.

Last month, Microsoft issued a security advisory urging companies to keep their Exchange Servers updated to block cyberattacks. It should prevent hackers from stealing critical and sensitive stored in their mailboxes and address books.
