Steven Sinofsky, Microsoft senior vice-president of Office, said, "Thanks to customer feedback we have improved product reliability by taking action on the top issues affecting product performance."
Benefits include better spam control and tighter integration of the main Office 2003 applications with Onenote and Infopath.
SP1 improves the junk e-mail controls introduced in Outlook 2003, allowing users to better manage incoming messages and filter spam by moving messages to a junk e-mail folder.
Outlook 2003 users can also automatically add the names of e-mail reply recipients to the Safe Sender list to ensure that future e-mails are routed properly.
Additional tools for managed code and enhanced support for XML will enable developers to create Infopath-based solutions more easily and quickly.
