Add the default outlook signature in the email generated
Take a look at the link below. It explains where the signatures can be found in the file system as well as how to read them properly.

The thread only mentions Window XP and Windows Vista signature locations. I have confirmed that Outlooks signatures on Windows 7 live in the same place as Vista. I have also confirmed that the signature location is the same for Outlook 2003, 2007, and 2010.
Here's a code sample if you choose to go this route. Taken from this site.
private string ReadSignature()
{
string appDataDir = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) + "\\Microsoft\\Signatures";
string signature = string.Empty;
DirectoryInfo diInfo = new DirectoryInfo(appDataDir);
if(diInfo.Exists)
{
FileInfo[] fiSignature = diInfo.GetFiles("*.htm");
if (fiSignature.Length > 0)
{
StreamReader sr = new StreamReader(fiSignature[0].FullName, Encoding.Default);
signature = sr.ReadToEnd();
if (!string.IsNullOrEmpty(signature))
{
string fileName = fiSignature[0].Name.Replace(fiSignature[0].Extension, string.Empty);
signature = signature.Replace(fileName + "_files/", appDataDir + "/" + fileName + "_files/");
}
}
}
return signature;
}
Edit: See here to find the name of the default signature for Outlook 2013 or @japel's answer in this thread for 2010.
There is a really quick easy way that hasn't been mentioned. See modified below:
public static void GenerateEmail(string emailTo, string ccTo, string subject, string body)
{
var objOutlook = new Application();
var mailItem = (MailItem)(objOutlook.CreateItem(OlItemType.olMailItem));
mailItem.To = emailTo;
mailItem.CC = ccTo;
mailItem.Subject = subject;
mailItem.Display(mailItem);
mailItem.HTMLBody = body + mailItem.HTMLBody;
}
By editing the HTMLBody after you display the mailitem you allow for Outlook to do the work of adding the default signature and then essentially copy, edit, and append.
