When was the Exchange Admin Center introduced?

The Exchange Admin Center (EAC) was introduced with Exchange Server 2013, marking a significant shift from the previous management tools used in earlier versions. The EAC offers a web-based management interface that provides administrators with a more user-friendly and intuitive way to manage Exchange environments. This change was crucial as it allowed for better navigation and integration of various administrative tasks, making it easier for users to manage mailboxes, configure settings, and monitor system health.

In Exchange Server 2010, the management was primarily conducted through the Exchange Management Console (EMC) and the Exchange Management Shell (EMS), which did not provide the same level of web-based interaction that the EAC offers. Subsequent versions like Exchange Server 2016 and 2019 built upon the foundation established in 2013, enhancing and refining the EAC, but they did not introduce it. The introduction of the EAC in Exchange Server 2013 thus marked a pivotal development in the management of Exchange environments.
