List All Public Folders

You can configure an IMAP4 server to list all public folders. You may not want to use this feature with clients that have problems listing a large number of folders. If you choose not to list all folders, Exchange lists only the client's private folders.

Note   Only public folders that have a replica on the user's public folder server are displayed in response to an IMAP4 LIST " "* command. If a replica does not exist on the user's public folder server, the public folder is available only to IMAP4 clients that are referral-enabled. IMAP4 clients can also access the public folders if IMAP4 servers are set up in a front-end/back-end configuration.

To list all public folders:

1. Start System Manager
   on the Start menu, point to Programs, point to Microsoft Exchange, and then click System Manager.
2. Navigate to IMAP4.
