System.DirectoryServices msExchRecipientTypeDetails getting its value.

Hello,

I am trying to get the value for msExchRecipientTypeDetails from my local active directory. I am using the following C# code. However instead of returning the integer value of the msExchangRecipientTypeDetails as a string it is returning a COM object.

Can someone explain why this is the case and help me with a solution. Every other property is returning with a value. Include msexchagneRecipientDisplayType.

Thanks

 
_adObject = new DirectoryEntry(DirectoryObjectString);
msExchRecipientTypeDetails = _adObject.Properties["msExchRecipientTypeDetails"][0].ToString();
