Microsoft reminded that the lifecycle of its email server software Exchange Server 2013 will end on April 11th 2023, and its users only have 31 days left to complete the migration work. Microsoft recommends customers migrate to Exchange Online or Exchange Server 2019. Customers who choose to migrate to Exchange Online will be eligible for Microsoft FastTrack – it provides tools and resources for seamless migration.
Although support is about to end, Microsoft confirmed that Exchange Server 2013 software will continue to run after the expiration date. But this poses a security risk because Microsoft will no longer provide security updates, bug fixes or technical support for it.
