Hi all, I just wanted to thank everyone once again for all your help. It turns out that my IP dept does not agree that it is a networking issue and insists it is an issue with my system. So, I guess I will be assimilated into using Outlook whether I like it or not. Thanks very much for the education in networking and e-mail. At least I learned a lot through this ordeal.
