Microsoft is now making available the Exchange Server Service Pack 2 software, that updates the Microsoft Exchange 2003 servers to the latest version. The software provides enhancements in mobility, spam protection and mailbox management.
Exchange SP2 offers a leap forward in mobility capabilities. With SP2, Exchange Server 2003 can offer a significantly improved Microsoft Outlook experience on mobile devices as well as additional security and device control.
The mobility enhancements in SP2 give users a new seamless Direct Push Technology e-mail experience.

Additional data compression translates into a faster experience when sending and receiving messages and reduced sync times.
The new version also provides greater control over mobile device security, including policy settings that allow to unlock a device with a password; local wipe, including incorrect logon attempts control; and remote wipe, that allows administrator to remotely delete information from lost, stolen, or misplaced mobile devices.
The update also provides new optional support for certificate-based authentication to eliminate the need to store corporate credentials on a device and support for Secure/Multipurpose Internet Mail Extensions (S/MIME) to sign and encrypt messages coming to and from mobile devices.
The updated and integrated Exchange Intelligent Message Filter is now based on the same SmartScreen filtering technology developed by Microsoft Research and incorporated in Microsoft Office Outlook 2003, MSN Internet Software and Services, and MSN Hotmail. Improvements to this filter ensure a continued focus on identifying spam and reducing false positives. These updates include new capabilities in the fight against spam including blocking phishing schemes. Phishing schemes attempt through deception to fraudulently solicit sensitive personal information by masquerading as legitimate Web sites.
To protect mailboxes against unsolicted emails (spam), the new support for Sender ID e-mail authentication protocol helps prevent unwanted mailbox phishing and spoofing schemes by verifying the IP address of the e-mail sender against the purported owner of the sending domain.
Administrators will welcome the increase in mailbox storage size limits to 75 gigabyte (GB) for Exchange Server 2003 Standard Edition. A new offline address book format offers significantly improved performance particularly when Outlook clients are operating in cached mode.
