I am using the evaluation edition of MS Exchange Server sersion 5.5. When I am trying to send mail using Outlook, Exchange Client, or the web the mail just remains in the outbox. I already asked a question like this in the catagory Outlook. But I think it hasn't anything to do with my client because I also tried Outlook Web Access and that is running on the server. Is it possible that it has something to do with my server settings? For Example the Information Store service or MTA. Maybe it is because I am using the evaluation edition (5.5 build 1960.5)? Can anyone tell what I am doing wrong? I am getting desperate!!!!
