STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.



MORE INFORMATION
The Fixmapi.exe tool, included with Microsoft Internet Explorer 5 and Outlook 2000, will detect and aid in resolving conflicts with MAPI files that may affect your ability to send and receive mail and faxes from other programs.
