Hi sumeethp, I recall answering a question from you about the Attributes property.  I forgot that a custom exception handler doesn't have this.  But you can still get the value of the Attributes property you specified in the config by providing a constructor which takes a NameValueCollection parameter.  Assign it then to a class level variable.

public class CustomMsmqHandler : IExceptionHandler
    private NameValueCollection attributes;
    public CustomMsmqHandler(NameValueCollection attributes)
            this.attributes = attributes;
