The reminder is triggered earlier than expected when an Exchange Server 2007 server receives an iCalendar meeting request message over an SMTP server
Article ID: 950409 - View products that this article applies to.
Consider the following scenario:
This problem occurs because the iCalendar body part in the message that is received from an SMTP server does not specify a VALARM property. Therefore, Exchange Server 2007 does not cause the reminder to remain in the calendar appointment when the request is processed by the calendar assistant. This condition causes the default reminder to occur within 15 minutes of receipt.
To resolve this problem, install Update Rollup 4 for Exchange Server 2007 Service Pack 1 (SP1). For more information about Update Rollup 4 for Exchange Server 2007 Service Pack 1, see the following Exchange Help topic:
