I need to create a mailbox (but not wanting to create an actual user account and mailbox in SBS Console) so that some users can access that mailbox from their OUTLOOK2003.
So I opened Exchange Management Console / Recipient Configuration / Mailbox and ran New Mailbox wizard and ran "User Mailbox" wizard and completed the process. For testing, I added myself (network admin) to both "Manage Send As Permission" & "Manage Full Access Permission" lists.
Then (I am not sure if this was redundant ...), open Active Dir Users and Comp.
Open the properties of the new email account and chose Mail Flow Settings / Delivery Options and selected myself in the "Grant this permission to:" list on the Send on behalf section.
When I click File/Open/Other User's folder and chose the new email account from the Select Name window/Global Address List in my OUTLOOK 2003, I get an error "Unable to display the folder. The Inbox folder could not be found".
