C# - How to include Outlook signature in an email that contains images?

Question

Here is my code to send the email in Outlook 2013:

public void GenerateEmail(OutEmail outEmail)
{
    var objOutlook = new         


        

Answer 1

try below mentioned

mailItem.GetInspector.Activate();
var signature = mailItem.HTMLBody;
mailItem.HTMLBody = EmailBody + signature;

Answer 2

Outlook inserts the signature when you call MailItem.Display or access MailItem.GetInspector (you do not have to do anything with the returned object).

If you want to programmatically insert a signature, Redemption exposes RDOSignature object which implements ApplyTo method.

UPDATE: as of the latest (Summer 2017) builds of Outlook, GetInspector trick no longer works. Now only MailItem.Display adds the signature to an unmodified message.
