EX 5.5 sp4 and outlook98 clients and read incoming html mail

[bironhead]

We have ex5.5 sp4 and use OL98. When ever we get an email with html code in it we just see the actual html code. Q183668 states the following with no resolution. Please help.
SYMPTOMS
If you use Microsoft Outlook 98 configured with the Corporate/Work Group installation and you have chosen HTML as the message format, some aspects of this message format will not be retained when viewed by the recipient. The MORE INFORMATION section outlines features that do not function under various transport options and makes comparisons with some other mail clients including other versions of Outlook.

CAUSE
This occurs as a result of an interaction between Microsoft Exchange Server version 5.5 and its Internet Mail Service.
