To access a shared folder that isn't one of the folders listed on the File |
Open | Other User's Folder dialog, the mailbox owner needs to grant Reviewer
permission to the root of the mailbox, as well as appropriate permission on
the folder.
The user who needs access then goes into Tools | E-mail Accounts or Tools |
Services (depending on the Outlook version), brings up the properties for
the Exchange Server service, and on the Advanced tab, adds the mailbox.
After that, the user will see in the folder list all those folders in the
secondary mailbox to which he/she has access and can add any of those
folders to the Outlook Bar. See
