The ServerVersion element represents the version number of the computer that is running Microsoft Exchange Server.
Response (POX)
Account (POX)

ServerVersion (POX)
<ServerVersion/>
The ServerVersion value is only valid if the Type (POX) element is equal to EXCH or EXPR. The ServerVersion value is a hexadecimal number that contains the MajorVersion, MinorVersion, and MajorBuildNumber of the server.
The following example coverts a ServerVersion value that is returned in an Autodiscover response to obtain and display the MajorVersion, MinorVersion, and MajorBuildNumber. This example enables you to enter a hexadecimal value for the ServerVersion value. If no ServerVersion value is entered, a default ServerVersion value of 738180DA is used.
static void Main(string[] args)
{
// Convert a ServerVersion value that is returned from an Autodiscover request.
// The value is a hex value and can be converted to the MajorVersion, MinorVersion,
// and MajorBuildNumber.
Console.WriteLine("Enter ServerVersion returned from the Autodiscover (eg. 738180DA) and Enter.");
Console.WriteLine("To use the default ServerVersion of 738180DA, just hit Enter.");
// Get the hexadecimal ServerVersion value.
string serverversionhex = Console.ReadLine();
// If nothing is entered, use the default server version of "738180DA"
if (serverversionhex == "")
{
serverversionhex = "738180DA";
}
Console.WriteLine("ServerVersion (Hex) = " + serverversionhex);
string serverversionbinary = Convert.ToString(Convert.ToInt32(serverversionhex, 16), 2);
// The ServerVersion (binary) should be 32 bits in length. If the
// server version in binary is a length of 31 characters, the leading
// zero has been removed in the conversion process. Put the missing zero back.
if (serverversionbinary.Length == 31)
{
serverversionbinary = String.Concat("0", serverversionbinary);
}
Console.WriteLine("ServerVersion (bin) = " + serverversionbinary);
// The first 4 bits represent a number used for comparison against
// older version number structures. You can ignore this.
// The next 6 bits represent the major version number.
int majorversion = Convert.ToInt32(serverversionbinary.Substring(4, 6), 2);
Console.WriteLine("MajorVersion: " + majorversion);
// The next 6 bits represent the minor version number.
int minorversion = Convert.ToInt32(serverversionbinary.Substring(10, 6), 2);
Console.WriteLine("MinorVersion: " + minorversion);
// The next bit represent a flag - you can ignore this.
// The next 15 bits represent the major build number.
int majorbuild = Convert.ToInt32(serverversionbinary.Substring(17, 15), 2);
Console.WriteLine("MajorBuildVersion: " + majorbuild);
Console.WriteLine("\n\nPress any key to continue");
Console.ReadKey();
