"Microsoft Exchange Server 2013 Reaches End of Support"

Microsoft Exchange Server 2013 has reached end of support on April 11, 2023, and will no longer receive security patches.  The product will continue to work even after this date, but Microsoft stated that it is no longer providing technical support, bug fixes for usability and stability issues, time zone updates, and, importantly, fixes for vulnerabilities that could expose servers to hacker attacks.  Microsoft reminded users in February about Exchange Server 2013 approaching end of support, advising them to migrate to Exchange 2019 or Exchange Online (Microsoft 365 or Office 365).  The tech giant has provided detailed instructions for users who have yet to migrate.  The company has made no mention about extended support being available.  Microsoft stated that it is important that organizations stop using Exchange 2013, considering that the product has often been targeted in attacks, including by profit-driven cybercriminals and state-sponsored threat actors.
