How do i specify X-Headers for outgoing emails in Microsoft Outlook 2010

I need to include custom headers in my outgoing emails.

I'm using Microsoft Outlook 2010 and SendGrid SMTP server.

In particular, i want to specify a unique tracking ID on each mail using SendGrid's X-SMTPAPI header.

My Approach:

I am build an Outlook Add-In that will intercept outgoing emails and add the required headers Outlook.Application object has an ItemSend event that serves this purpose.

How do i use Mail.PropertyAccessor.SetProperty to set the custom headers? I am unable to find the correct header identifier that points to x-headers, or that will allow me set custom headers.

Your help is appreciated.

Thanks.

  • ReliefJet Essentials' Outlook rules integration allows that. You just create an outgoing rule and select ReliefJet Essentials' Set Header Value tool as a custom action. That's all!
