In my OWA folder list, I see something called Public Folders. What are Public Folders?
Public Folders are shared mail folders that reside on the Exchange server. If you can see public folders then your account has appropriate permissions to view public folder hierarchy—but you may not have permissions to read the messages stored in the public folder. Several University departments maintain public folders to provide shared access to mail messages. If you see a public folder that you’d like to have access to, please contact that department to learn whether your account can be assigned appropriate permissions.
