When a message is sent from the Exchange server to the Groupwise, the API gateway strips the HTML tags and sends the message as plain text.
When a message is sent from Groupwise to Exchange, it creates 2 attachments, one plain text with all the HTML tags and the other is the text. The body of the message is blank.
The rest of the system is running fine and the client is not planning on getting rid of the Groupwise system anytime soon, they are migrating users slowly over the next year.
How can I correct the system so that HTML messages are not altered when passed between systems.
