We have Exchange 2003 and Outlook 2003. I have several users (A, B, & C) that need to have access to a shared user mailbox (D). I have opened user account (D) in Outlook and added A,B,&C to the delegates. I've given them the appropriate permissions. In each of the users (A, B, & C) accounts, I have gone to Tools\Email Accounts\View or Change\Change Microsoft Exchange Server\More Settings\Advanced Tab\Add User D.
For all three users the account appears in their folder list in Outlook, but it is unable to expand. Can anyone help me to figure out what step I am missing.
