When you use the Microsoft Outlook Web Access client and attempt to open an attached mail message, you receive the following error message
The attachment is a type not yet supported
and the attached message does not open. The Outlook Web Access client does not currently support opening attached mail messages that are in MSG file format. All attached messages will open correctly in the Exchange and Outlook clients.


The Outlook Web Access client does not currently support opening an attached mail message which is in the MSG file format.


You can use the Exchange Windows 3.x, Exchange Windows NT, or Exchange Windows 95 clients and the Outlook Windows 95 or Outlook Windows NT clients to successfully open attached mail messages.


Microsoft has confirmed this to be a problem in Microsoft Outlook Web Access, version 5.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
