I am trying to set up my outlook account on my new macbook pro. I can receive messages, but it wont allow me to send any messages. Every time I try get the error # 3259 "an operation on the server timed out. The server may be down, overloaded, or there may be too much net traffic." I think I have everything set up properly as it says to use the same outgoing settings as incomming.

What are you connecting with? What version, service pack and update rollup level is your Exchange server?Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."
