Configuring IMAP Public folders

To provide IMAP clients with access to a public mail database you first enable a database for IMAP use, and then specify the appropriate level of access to that database for users. Finally, you designate the database as an IMAP public folder. This procedure provides steps for configuring a database as an IMAP public folder.

Before you begin

Complete the following tasks:

About this task

After you have completed the prerequisite tasks, configure the database as an IMAP public folder.

To be configured as a public folder, a database must be created from a IBM® Notes® mail template. The IMAP service does not support the use of discussion databases as IMAP public folders.


  1. Make sure you already have a Configuration Settings document for the server(s) to be configured.
  2. From the Notes® client or IBM® Domino® Administrator client, select a database that has been enabled for IMAP access to be designated as an IMAP public folder and copy it as a database link.

    For example, from the Files tab of the Domino® Administrator client, double-click the database icon to open it, and then click Edit > Copy As Link > Application Link to copy the database as a link.

  3. From the Domino® Administrator, click the Configuration tab and expand the Messaging section.
  4. Click Configurations.
  5. Select the Configuration Settings document for the mail server or servers you want to administer, and click Edit Configuration.
  6. Click the IMAP > Public and Other Users' Folders tab.
  7. Complete the following fields and then click Save & Close:
    Table 1. Public folder fields
    Field Description
    Public folder prefix The name of the virtual root folder Domino® uses to organize the hierarchy of Notes® mail databases configured as IMAP public folders. When an IMAP client connects to the server it displays the public folders available to the user as subfolders of this folder.

    Unless you have a specific reason to change the folder prefix, accept the default name to ensure IMAP clients can access public folders on the server.

    Public folder database links Database links for IMAP-enabled Notes® mail databases you want to designate as IMAP public folders. Paste the database link copied in Step 2 into this field.

    For example, insert the cursor in the field and click Edit > Paste. The Notes® database represented by the link is now designated as an IMAP public folder. Users with the appropriate access privileges can open the database from an IMAP client.
