Secunia

http-equiv has reported a vulnerability in Microsoft Outlook 2003, allowing malicious people to perform illegal actions through emails.

Microsoft Outlook 2003 is supposed to protect the user by opening mails in the restricted security zone, thereby preventing the use of active scripting, download of files and more.

However, it is possible to bypass the security settings by embedding an OLE Object with reference to a Windows media file in a Rich Text Format (RTF) message. This can be exploited to start a download sequence of arbitrary files, which in turn causes Internet Explorer to prompt the user whether to download the file. However, combined with SA11572 "Predictable File Location Weakness", it is reportedly possible to launch the file without any warning.

This has been reported to affect Microsoft Outlook 2003. Other versions may also be affected, but they do not promise to protect the user in the same way.

Solution
The vulnerability has been silently patched at some point. Make sure the latest updates have been installed.
