This is not necessarily a C# question per se, but I posted this here in the hope that someone knows about this.
I am looking up Recipient.FreeBusy method in the Outlook library.

Here's my code.
C# Code:
  1. using System;
  2. using System.Linq;
  3. using Microsoft.Office.Interop.Outlook; //make sure to add a reference to the COM library Microsoft.Office.Interop.Outlook
  5. namespace OutLookFreeBusy
  6. {
  7.     class Program
  8.     {
  9.         static void Main(string[] args)
  10.         {
  11.             var outlook = new Application();
  12.             var mapi =  outlook.GetNamespace("MAPI");
  13.             var reci = mapi.CreateRecipient(""); //Replace this string with a valid email address
  14.             Console.WriteLine("String data:\n {0}", reci.FreeBusy(new DateTime(2013, 11, 27), 60 * 24, true));
  15.         }
  16.     }
  17. }

Now when I run my code, I get a valid string, but my question is to do with interpreting the string. I was expecting 24 characters to be returned with the snippet of code I posted, but I get 28 characters back.

From the documentation, each character represents 1 hour of activity. This is the part that is confusing me.
The string I get looks like this
PHP Code:
I counted the characters from different email addresses. Each time I get different values, but the total count stays at 28.
