Outlook 2000 and 2003 clients cannot send any messages. But they are receiving fine. When they click in the send button, they have the message "Outlook is retriving data from the Exchange Server". It will try until you say to cancel the request.
Exchange Server 5.5 under Windows NT 4.0.
Last weekend I cleaned up some old log files, and also I deleted some very old user's profile, not in use anymore.
Can you help me?
