• The user's personal mail file
• Other users' personal mail files to which the user has been delegated access
• Public mail files, such as mail-in databases, to which the user has access, and which are set up as IMAP public folders.

Note To provide IMAP users with access to other users' mail files, you must use a Notes client or Domino Web Access client to delegate mail file access. It is not sufficient to add the names of users to the ACL of the mail file.

Enabling clients that do not support the NAMESPACE extension to access shared folders

By default, only IMAP clients that support the NAMESPACE extension can display mail files other than the user's personal mail file. However, you can configure the IMAP service so that it presents public and others users' folders even if the user's IMAP client does not have built-in NAMESPACE support. Configured in this way, the IMAP service always returns to the client the complete range of mail folders to which the current user has access.

To enable IMAP NAMESPACE support on the server

1. Make sure you already have a Configuration Settings document for the server(s) to be configured.

2. From the Domino Administrator, click the Configuration tab and expand the Messaging section.

3. Click Configurations.

4. Select the Configuration Settings document for the mail server or servers you want to administer, and click Edit Configuration.

5. Click the IMAP - Public and Other Users' Folders tab.

6. In the Basics section, complete the following field and then click Save & Close:

Field	Enter
Public and other users' folders support	Choose one: Enabled - (default) In addition to presenting an IMAP client with the current user's mail folder, the IMAP service also presents any public folders and other users' mail files that the current user has access to. Disabled - The IMAP service does not present IMAP clients with public and other users' mail folders. The IMAP client can access the current user's personal mail file only.
Include all public and other users' folders when a folder list is requested	Choose one: Enabled - The IMAP service always displays all available folders to the connecting client. Disabled - (default) The IMAP service displays available folders in the Other users' and Public namespaces only to clients that request them using the NAMESPACE command. If a client does not support the NAMESPACE command, the IMAP service presents to it the current user's personal mail folder only. Note This field is not available if "Public and other users' folders support" is set to Disabled.

Note These settings apply to Domino Release 7 and later only.

Changes take effect after the next IMAP update interval. Sessions that begin after the updated settings take effect use the updated settings. However, existing sessions continue to use the settings that were in effect when the session started.

For information on setting the IMAP update interval, refer to the appendix NOTES.INI File.
