Messages without attachments are being sent without any problems. When an
attachment is added the send procedure takes a very long time and ends in
"networking problems prevent connection to exchange server". The problem
occurs on some PC's and is not related to the user. Therefore, it seems to
be a problem on the client. Is there anyone who can give me a clue?
I posted this problem before but at that time I had SP2 installed. Someone
told me to try SP4 but it did not solve the problem.
