SYMPTOMS

When a Microsoft Exchange Server 2007 user sends a recurring meeting request or a recurring appointment to an external recipient, the recipient may find that the last occurrence of the meeting request or the appointment is missed. This problem occurs when the following conditions are true:
  • The mailbox of the external recipient is not hosted on an Exchange server.
  • The recurring meeting request or the recurring appointment has a specific End by day.
  • The End by day is set to the same day as the date of the last occurrence.

CAUSE

This problem occurs because Exchange Server 2007 has to convert the meeting request or the appointment to an iCalendar message for external recipients. Exchange Server 2007 uses the DateTime.Date property to set the end time. In this case, Exchange Server 2007 sets the End by day time as the begining of a day instead of the end of a day. When the End by day is set to the same day as the date of the last occurrence, the date of the last occurrence is out of the correct range. Therefore, the external recipient misses the last occurrence.

RESOLUTION

To resolve this problem, install the following update rollup:
979784 Description of Update Rollup 3 for Exchange Server 2007 Service Pack 2

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
