I did a forward setting in my exchange server. I think it is successful, because it was able to forward email to my private mailbox. But it only can forward internal email to my private mailbox, if from external mailbox, it could not. For example, system can forward my colleagues' email from internal, but it was unable to forward suppliers' or customers' from external. It is very strange, I can make sure my account has no problem to send and receive external email, and the forward function can works. Is it has something wrong of the setting?
help me please, thanks a lot.
