RIM have released SP2 for BES 5 for both Microsoft Exchange and Lotus Domino flavours. Weighing in at 668MB (for Exchange) and 678MB (for Domino), the update is a complete copy of the BES software.

Both updates can be downloaded free of charge from the BlackBerry web site - http://blackberry.com/go/serverdownloads

New features for Microsoft Exchange deployments include:

• Automatic discovery of Exchange Web Services - The BlackBerry Messaging Agent can discover Microsoft Exchange Web Services automatically and use it to synchronise calendar data (replacing the now deprecated MAPI CDO API)
• MDS Connection Service Integrated Authentication - When BlackBerry device users need to access internal network resources from their devices, the MDS Connection Service can be configured to authenticate users using their Windows account credentials
• Administrative Groups - The BlackBerry Administration Service includes new default groups that have preconfigured roles that you can add different types of administrative accounts to. The default groups help make sure that users without administrative privileges cannot escalate their permissions.
• Enhancements to activation and prepopulation - The BlackBerry Messaging Agent now monitors the Junk Mail folder as well as the Inbox for activation messages. You can now configure the BES to prepopulate a maximum count of 3000 email messages and a maximum message age of 30 days
• Enhancements to S/MIME encryption - If users configure S/MIME encryption on their devices, you are no longer required to turn on S/MIME encryption on the BES before the BES can begin processing S/MIME protected messages
• Enhancements to SRP connections - When you install a BES or start the BlackBerry Dispatcher Service, the BES verifies whether the SRP ID is currently in use by another BES already. If it is in use, the BES does not open the SRP connection
• Enhancements to the synchronisation of email message content - The BES forwards the full content of email messages that are sent from email applications to the device, rather than just the message header and subject
• Enhancements to the BlackBerry Administration Service - If an administrator enters their password for the BAS incorrectly 10 times in succession, the administrative account is locked for 15 minutes and the administrator cannot log in
• Enhancements to the BlackBerry Web Desktop - If you configure the appropriate option in the BlackBerry Administration Service, the BlackBerry Web Desktop Manager permits users to perform the following self-service tasks: specify a new device password and lock the device; delete all device data and disable device
• Support for Single Sign On authentication - Access to both the BlackBerry Administration Service and the BlackBerry Web Desktop can be managed automatically using Windows credentials
• Microsoft SQL Server 2008 R2 is now supported
• The default body size of calendar entries that the BES synchronises with devices is now larger
• Support for web browsers - The BlackBerry Administration Service can now be accessed from web browsers other than Internet Explorer, including Safari, Firefox and Chrome - NOTE Internet Explorer is still required for management of devices locally via USB
• Microsoft Windows Server 2008 R2 is now supported
