The customized properties are removed in the recipients' calendars when you send a meeting request that includes customized properties

In a Microsoft Exchange Server 2007 environment, when you send a meeting request that includes customized properties, these customized properties are removed in the recipients' calendars. If you compare the meeting request in the recipients' Inbox and Calendar by using MAPI Editor, you may find that the customized properties exist in a message in the Inbox. However, the meeting request does not appear in the Calendar item.

To resolve this problem, install Update Rollup 7 for Exchange Server 2007 Service Pack 1.
