Windows Sbs2003 Server sp2 for windows and sp2 for exchange. The problem i have is some users can send and recieve e-mails fine and some users can't. The users that can't , problems are as follows they can send internal and external e-mails but cannot recieve internal or external e-mails. There is a local queue on exchange and i believe this is where there mail is sitting but cannot get it to deliver the mail, tried to force mail no joy and no errors in event log pointing to a problem. Have tried removing the account on pc and recreating no joy. Re-applied sp2 for exchange on server no joy. Any ideas or help appreciated ?
