“The best option is to have replaced the application before it reaches the end of support,” said Parkin. With updated versions of Exchange and Exchange Online being superior alternatives, there’s no reason to stay with Exchange 2013, said Mike Parkin, senior technical engineer at Vulcan Cyber. “This trend points to the increased attractiveness of migrating to cloud-hosted messaging services like Microsoft Exchange Online or Office 365, which are much easier to maintain - and keep secure,” said Neray. Phil Neray, vice president of cyber defense strategy at CardinalOps, said recent attacks on Exchange servers, such as the one perpetrated by the Play ransomware gang on Rackspace, highlight the continued vulnerability of these older on-premises systems. 'This might be because of regulatory requirements, to guarantee data isn't stored in a foreign datacenter, because you have unique settings or requirements that can't be met in the cloud, or because you need Exchange to manage cloud mailboxes because you still use Active Directory on-premises.' But we understand that some organizations need to keep some Exchange servers on-premises,' the road map states. 'We strongly believe that you get the best value and user experience by migrating fully to Microsoft 365.

While Exchange Server 2013 will continue to run after April 11, because of the potential security risks, the company “strongly recommends” that businesses migrate as soon as possible.

Those options include migrating to Microsoft 365 or upgrading on-premise Exchange servers to more updated 2019 version. Last year, the company developed an end of support roadmap to help prepare Exchange 2013 customers for the cut-off date. Microsoft also continues to support Exchange Server 2019 for customers with on-premises requirements.Īccording to an announcement earlier this week, after April 11 Microsoft will no longer offer technical support for problems that may occur, bug fixes for issues that may impact the stability and usability of the server, security fixes for newly-discovered vulnerabilities or time zone updates. The software giant encouraged customers to move to Exchange Online to benefit from cloud-driven performance and security updates. Microsoft confirmed on Thursday that it will not offer extended support for Exchange Server 2013 after April 11.
