In IBM Lotus Notes, users can include document links, anchor links, view links, or database links (application links) in their email messages. BlackBerry Enterprise Server version 4.1 SP6 supports IBM Lotus Notes links in the email messages that users receive on their BlackBerry devices. The BlackBerry Enterprise Server retrieves the target information from the appropriate IBM Lotus Domino server and converts it into HTTP format. In plain text messages, the link appears as a web address. In HTML messages, the link appears as an icon.

Requirements

• BlackBerry Enterprise Server version 4.1 SP6
  
  
• Any IBM Lotus Domino servers containing the target information must have the HTTP task running
  
  
• Any IBM Lotus Domino servers containing the target information must be configured to allow browser clients to access databases on the servers 

Turn on support for IBM Lotus Notes links

The BlackBerry Enterprise Server detects the IBM Lotus Domino servers that user accounts are assigned to and updates the map of IBM Lotus Domino server names and host names accordingly so that it can access the target information on these servers. If the BlackBerry Enterprise Server cannot detect an IBM Lotus Domino server (for example, if an IBM Lotus Domino server is in a different domain), you can add the IBM Lotus Domino server name and host name to the map manually using a registry value.

1. On the computer that hosts the BlackBerry Messaging Agent, on the Start menu, click Run.
2. Type regedit.
3. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Research In Motion\BlackBerry Enterprise Server\Agents.
4. If necessary, create a registry key that is named DocLink.
5. In the DocLink registry key, create a multistring value that is named ServerHostNames.
6. Double-click the new multistring value.
7. In the Value data field, type the IBM Lotus Domino server name and host name using the following format: <servername>!!<hostname> (for example, CN=server01/O=central!!test.rim.net). Type additional server names and host names on separate lines.
8. Click OK.

Change how often the map for IBM Lotus Domino server names and host names updates

By default, the map that the BlackBerry Enterprise Server uses to access target information on IBM Lotus Domino servers updates daily at 3:00 AM. You can use a registry value to change how often the map updates.

1. On the computer that hosts the BlackBerry Messaging Agent, on the Start menu, click Run.
2. Type regedit.
3. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Research In Motion\BlackBerry Enterprise Server\Agents.
4. If necessary, create a registry key that is named DocLink.
5. In the DocLink registry key, create a DWORD value that is named ServerHostNamesCacheTimeout.
6. Double-click the new DWORD value.
7. In the Value data field, type the interval, in seconds, that the map updates itself.
   The minimum value is 3600 seconds (1 hour); the maximum value is 86,400 seconds (24 hours).
8. Click OK.

Turn off support for IBM Lotus Notes links

1. On the computer that hosts the BlackBerry Messaging Agent, on the Start menu, click Run.
2. Type regedit.
3. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Research In Motion\BlackBerry Enterprise Server\Agents.
4. If necessary, create a registry key that is named DocLink.
5. In the DocLink registry key, create a DWORD value that is named Disable.
6. Double-click the new DWORD value.
7. In the Value data field, type 1.
8. Click OK.
   

After you finish: To turn on support for IBM Lotus Notes links, change the Disable registry value to 0.
