Dear Friends, I have a small problem with my exchange 5.5. Some of my exchange users are not able to receive e-mails from internet. Secondly, the same users are also not able to send and receive e-mails to each other internally, whereas their e-mails are going to wrong recipients of our exchange server. It is a strange kind of problem. But we need an urgent solution to this. There are no events in even log. Kindly help. Regards Rajnish Malik
