I am trying to open an additional mailbox in Outlook 2003 for one of my users. She already has three additional mailboxes in the list (found in the advanced account settings), and these work fine. When I click the "Add..." button, it immediately reports:
The name could not be resolved. The action could not be completed.
This is before I am prompted for the name.
We're using an externally hosted Exchange 2007 server.
How do I resolve this?
