The purpose of the BlackBerry Enterprise Server is to centralize management and control of the BlackBerry solution within an organization. The BlackBerry Enterprise Server performs the following functions for each user:

1. Monitors the user’s mailbox for new email.
2. Applies user-definable filters to new messages to determine if and how the message will be relayed to the user’s BlackBerry Wireless Handheld.
3. Compresses and encrypts new messages and pushes them to the BlackBerry Wireless Handheld via the Internet and wireless network.
4. Receives, via the Internet, messages composed on the BlackBerry Wireless Handheld, then decrypts and decompresses the messages and places them in the user’s Outbox for the corporate

Microsoft® Exchange Server to deliver

The BlackBerry Enterprise Server provides a secure, two-way link between the user’s Microsoft Exchange account and the user’s BlackBerry Wireless Handheld. Consider the BlackBerry Enterprise Server as a conduit rather than a mail server or message repository – all message storage is still left to the Microsoft Exchange Server. By maintaining a link to the messages in the user’s Microsoft Exchange mailbox, the BlackBerry Enterprise Server provides several advanced features:

1. When forwarding a message from the handheld, the BlackBerry software forwards the complete original message from the user’s Microsoft Exchange account, including all attachments that are appended to the message. Although attachments cannot be viewed on the handheld, they can still be forwarded to other email addresses.
2. When receiving a message from the handheld, the first 2K of a message are pushed to the handheld. The user is able to request more of the message to be delivered in 2K blocks up to a maximum of 32K.

When “replying with text” from the handheld, the BlackBerry software will append the entire original message to the reply, not just the 2K that was sent to the handheld.

The BlackBerry Enterprise Server is a Windows® NT service that can monitor many users at once over a single administrative connection to the Microsoft Exchange Server. The BlackBerry Enterprise Server uses a direct TCP/IP connection to the wireless network. Achieving this direct connection requires a one-time configuration of the company firewall and results in a considerable speed advantage. Figure 1 provides an overview of the system architecture. At the heart of this wireless email solution is the BlackBerry Enterprise Server:

1. The BlackBerry Enterprise Server is administered through extensions to the standard Microsoft Exchange Administrator
2. The configuration information is placed in the data store of an Administration account
3. That must be set up for the BlackBerry Enterprise Server. This account must have privileges to read and write to the message stores of the users it serves.
