Mike and others,
A big thank you for your time and efforts trying to help with this and other issues. I am happy to say that this issue has been resolved! Our IT department found a firewall issue that was blocking the email.
Whew! And just in time. This WW install is on our backup server. Just today we had a full server crash on our main production server. I am hoping to get that fixed, but in the mean time our faculty can recreate their courses on our backup server and use it until production server/WW issues are resolved.
Thanks again, this forum has really been helpful.
