Most Microsoft products have a support lifecycle during which they get new features, bug fixes, security fixes, and so on. This lifecycle typically lasts for 10 years from the product's initial release. The end of this lifecycle is known as the product's end of support. Because Exchange 2013 end of support on April 11, 2023, Microsoft will no longer provide the following after this date:

• Technical support for problems that may occur.
• Bug fixes for issues that may impact the stability and usability of the server.
• Security fixes for vulnerabilities that may make the server vulnerable to security breaches.
• Time zone updates.

Your installation of Exchange 2013 will continue to run after this date. But because of the changes listed above, we strongly recommend that you migrate from Exchange 2013 to Exchange 2019 as soon as possible.
