Here is the scenario:
Two companies have partnered and share a couple of outside sales representatives.
The sales representatives are fully employed by company A and only receive commission only on sales leads that come through company B. When the sales representative responds to the leads from company B they need to do so using company B's exchange server (no problem as they have access to OWA).
Company A doesn't allow any POP3 access on their domain.
All emails that are sent to the reps account at company B should be auto forwarded to the email address for the sales representative at company A with a notation stating the email / lead is from company B.
Any ideas how to do this using Exchange vs. Email Rules inside each sales reps account if this is possible.
