Consider the following scenario:

•	Mailboxes are located on a Microsoft Exchange Server 2007-based server.
•	The organizer sends a meeting request to attendees. In addition, the organizer granted Editor permissions to an attendee on the Calendar folder.
•	The attendee who was granted Editor permissions accepts the meeting request.
•	This attendee uses a Web services application to update the meeting. However, the attendee does not update the meeting time.

In this scenario, you find that the time of an update meeting request is incorrect if the attendee uses a Web services application to modify an appointment item. If the organizer modifies the appointment item, the time is correct.

This problem occurs because Web services does not use the correct time zone information. In this case, incorrect start times and end times occur when the meeting request is updated.
