The end of support for Exchange Server 2010 has been extended from January 14th, 2020 to October 13th,2020 to give customers more time to complete their migrations. This extension also aligns with the end of support for Office 2010 and SharePoint Server 2010.
For those ready to move to the cloud, we recommend Office 365 and Exchange Online for continuous support and servicing. For those moving to a new version of an on-premises server, we recommend moving directly to Exchange 2016 to remain supported through 2025.
After October 13th, 2020, Microsoft will no longer provide technical support for Exchange Server 2010, including bug fixes, security fixes, and time zone updates. Your installation of Exchange 2010 will continue to run after this date. However, we recommend upgrading to Exchange Server 2013 or ideally 2016 to remain secure and supported.
