SYMPTOMS
When you send a meeting request in iCalendar format from a Post Office Protocol 3 (POP3) account in Microsoft Outlook to a user on a Microsoft Exchange 2000 Server computer, the Content-Type:text/calendar information is not recognized, and it is added as text to the body of the message. For example, when the recipient opens the message in Outlook, text that is similar to the following text is added to the body of the message:

BEGIN:VCALENDAR

PRODID:-//Microsoft Corporation//Outlook 10.0 MIMEDIR//EN

VERSION:2.0 METHOD:REQUEST BEGIN:VEVENT This problem does not occur when you send the meeting request to a user on an Exchange Server computer.



CAUSE
This problem may occur if the meeting request is sent through the Internet Mail Service on the Exchange Server computer to the Exchange 2000 computer, and the Internet Mail Service is configured to route only incoming messages. Exchange Server does not recognize or understand the iCalendar format. As a result, the message is not processed correctly, and the Content-Type:text/calendar information is added as text to the body of the message.



RESOLUTION
To resolve this problem, configure the Internet Mail Service to re-route messages through an Exchange 2000 computer.
