We are running Exchange 2003 Ent SP2 and most of our clients are Outlook 2003.
We have a user that is having problems with the Entourage client has recently been displaying this message every time he sends a message.
Entourage error: An unknown error (4363) occurred.
Mail could not be sent.
Account name: "(my name)"
It occurs every I am getting an email error message when sending an email from Entourage. My email is actually being sent, but I receive a pop up message (attached) that says the mail could not be sent.
Has anyone had this experience before and know how to solve it?
