Bizarre Outlook emailing issue

Question

I'm using the Outlook and Redemption libraries to send emails in a program I've written. I have everything working now for the most part. I am able to send emails. I'm running into an issue, though. I'm sending the email from an exchange account on a different server. To test my program, I'm sending it to two outside (gmail, yahoo) accounts and one internal email (my internal exchange email). The email received to the internal account has a messed up To: field. Rather than have the semi-colon delimited list of addresses the email was sent to, it has " ; ; <My Name>", where it doesn't display the external email addresses, but shows my name I'm guessing it pulls from the internal email directory. When the email is received by the external email accounts, it shows all three email addresses in the To: field.

Another weird thing… when I run the program on my computer, where it sends the email using my exchange account, all three recipients are displayed. It shows the external email addresses in single quotes and my name from the directory for my internal email address.

What gives?
