http-equiv has reported a security issue in Microsoft Outlook, potentially allowing malicious people to place a file in a predictable location.

The problem occurs when a user replies to an email with an embedded HTML file, since the embedded HTML file is saved in the current users "Temp" directory using its original file name.

Normally, this behaviour doesn't pose a problem, and the issue would have been rated "Not Critical". However, certain vulnerabilities and inappropriate shell folder functionality in Internet Explorer allows malicious people to execute arbitrary code placed in the embedded HTML file with the privileges of the current user, if the user visits a malicious website using Internet Explorer.

Solution
This has reportedly been silently fixed by one of the latest Office updates dated 14th May or 17th May.
