This is a RE-POST as I have still not been able to resolve this problem. Thanks :-) Hi everyone, Exchange 2000 / users on Outlook 97 I have a weird thing going on. My email enabled groups that worked when I created them 2 months ago have stopped working. When you send an email to the group it shows up in your sent items (not in outbox) but never gets to any of the users. Email sent to people by selecting the names from the address list works as well as email in and out of the location. The only history here is that yesterday afternoon I had to turn off my entire network from 2pm until 8am this morning. I made sure that my domain controllers were the last to come down and the first to come up. I work for a State agency and we are part of the states Forrest. We run our own DNS, DCHP & WINS. Any ideas? Kim
