A few months ago, if you have an Exchange server and wanted to sync Blackberry Smartphones wirelessly, you would have to purchase licenses for the BlackBerry Enterprise Server.  Now BlackBerry has finally released BlackBerry Enterprise Server Express for no additional software or client access licensing cost.  For the end user, the only cost is the internet-enabled BlackBerry service plan from your wireless service provider.

The BlackBerry Enterprise Server Express has most of the features that you need such as:

• Synced inboxes (i.e., email deleted from work Outlook account are also deleted from your BlackBerry smartphone - no need to manage 2 inboxes)
• Ability to flag emails for follow-up from your BlackBerry smartphone
• Search your desktop inbox for messages from your BlackBerry smartphone
• Set up out of office replies from your BlackBerry smartphone
• Access and update important notes and tasks
• Access to an up-to-date calendar that is synched wirelessly (No need to tether to your desktop!)
• View, download and forward calendar attachments
• Wireless address lookup (changes to your corporate address book are reflected almost immediately on your BlackBerry smartphone)
• Synchronization between your desktop address book and your BlackBerry smartphone address book (that means when you add a contact to one, it is automatically updated in the other)

Below are the features that are not included with the BlackBerry Enterprise Server Express edition.  If you or your business require these features, you will have to purchase the full BlackBerry Enterprise Server.

• Enterprise Instant Messaging Clients
• Enterprise Social Networking Solutions
• Chalk® Pushcast Software
• BlackBerry® Mobile Voice System
