Microsoft Office 2003 Service Pack 1 is available at Downloads on Office Online. Under Office Update, click Check for Updates.

The following Outlook improvements are included with this Service Pack 1 release:

Junk E-mail Filter enhancements

The Automatically add people I e-mail to the Safe Senders List check box has been added to the Safe Senders List in the Junk E-mail Options dialog box. E-mail addresses of people who are not necessarily in your Contacts but are people whom you correspond with regularly are included in this list by default by selecting this check box. For more information, see "Junk E-mail Filter Lists" in About the Junk E-mail Filter.

The International tab has been added to the Junk E-mail Options dialog box. The tab contains two new lists — the Blocked Top-Level Domains List and the Blocked Encodings List — that allow you to block unwanted e-mail messages that come from another country or region or appear in another language. For more information, see "Junk E-mail Filter Lists" in About the Junk E-mail Filter.

Rules

Rules are now designed so that they do not act on messages that have been moved to the Junk E-mail folder. This new design keeps e-mail messages considered to be junk in the correct place rather than moving them to another folder according to the rule.

Additional attachment file types blocked by Outlook

The list of attachment file types that Outlook blocks for security reasons has been updated.
