Domino users cannot find meeting request attachments that are sent from Exchange 2007 users

In an Exchange Server 2007 and Domino Server coexistence environment, Exchange users and Domino users can send meeting requests to or receive meeting requests from one other. However, when Exchange users send Domino users a meeting request that has an attachment, Domino users cannot find the attachment.

The meeting request from Exchange server is processed as the iCalendar (iCAL) format and be transmitted in a MIME message. When Exchange Server 2007 generates the MIME message that has the embedded iCalendar object, it does not put the ATTACH property in the iCalendar object. However, Domino Server determines the presence of attachments by the ATTACH property in the iCalendar object.

To resolve this problem, install Update Rollup 5 for Exchange 2007 Service Pack 1. For more information about Update Rollup 5 for Exchange Server 2007 Service Pack 1, see the following Exchange Help topic: For more information about how to obtain the latest Exchange service pack or update rollup, see the following Exchange Help topic:
