Checking the version of Exchange is a crucial step in managing and maintaining a Microsoft Exchange Server environment. It allows administrators to determine the specific version and build of Exchange that is installed, which is important for applying updates, resolving issues, and ensuring compatibility with other systems.
The version of Exchange can be checked using various methods, including the Exchange Management Shell (EMS), the Exchange Admin Center (EAC), and the Get-ExchangeServer cmdlet. Each method provides a slightly different set of information, but they all essentially serve the same purpose of identifying the Exchange version.
