Workaround

To workaround these errors, create a new registry key by completing the following steps:

Warning: The following procedure involves modifying the computer registry. This can cause substantial damage to the Microsoft® Windows® operating system. Document and back up the registry entries prior to implementing any changes.

1. Open the Registry Editor, and locate HKEY_LOCAL_MACHINE\SOFTWARE\Research In Motion\BlackBerry Enterprise Server\Agents.
2. Create DWORD MaxTimeoutOnCalHelper (This key does not exist by default).
3. Specify a value of decimal 180.
4. Close the Registry Editor.
5. Restart the BlackBerry Enterprise Server.

Important: Restarting the BlackBerry Enterprise Server will delay email message delivery to BlackBerry smartphones. For more information, see KB04789.
