I have two mailboxes configured in one client machine in his Outlook 2007 (His own maibox and company generic mailbox), it is configured that he can choose any profile when he start the outlook (prompt for a profile to be used).
our exchange server is 2007.
the problem is he can send and receive emails from his account normailly but if he uses the company account he can receive but cannot send, putting in mind that I configured the send as permission from the server and full control also.
He gets undeliverble message please contact your administrator.
the mailbox qouta is fine and his Colleague can send and receive normally from the same company account.
