Improving the flow of email messages and calendar synchronization when the BlackBerry Enterprise Server runs on Windows Server 2008
The BlackBerry® Messaging Agent uses the CalHelper application to connect to the Microsoft® Exchange Server so that the BlackBerry Messaging Agent can synchronize calendars on BlackBerry devices with Microsoft® Outlook® calendars. In BlackBerry® Enterprise Server 4.1 SP6 and earlier and in BlackBerry Enterprise Server 5.0, the BlackBerry Messaging Agent uses the CDO.dll library to create temporary MAPI profiles that the CalHelper application can use to connect to the Microsoft Exchange Server to access users’ calendars.
In BlackBerry Enterprise Server 4.1 SP7 and BlackBerry Enterprise Server 5.0 SP1 and later, to improve performance, the BlackBerry Messaging Agent uses the MAPI32.dll library to create the temporary MAPI profiles.
After you install BlackBerry Enterprise Server 4.1 SP7 or BlackBerry Enterprise Server 5.0 SP1 or later, if you are running Windows Server® 2008 and notice that the limit that Windows Server 2008 places on NSPI connections is impacting MAPI performance and the flow of email messages, you can change how the BlackBerry Messaging Agent creates temporary MAPI profiles for the CalHelper application.
