I am running SBS 2003. My users run Outlook 2007 on their workstations.
One of our users has multiple mailboxes added to the default one. She can only send email from the main mailbox but not from the additional mailboxes. The problem occurs also if they 'reply' from these mailboxes.
I have tried to follow the advice here but on the server-user-properties, there is no 'security' tab.the error is
You do not have permission to send to the above recipient.Contact your system administrator for help..
Any advice will be appreciated.
