An incorrect pattern end date is returned when you use a WebDAV application to query the "patternend" property of a meeting request in Exchange Server 2003

When you use a Web Distributed Authoring and Versioning (WebDAV) application to query the patternend property of a meeting request, an incorrect pattern end date is returned. This problem occurs if the following conditions are true:

• The recurring meeting request is created when the End after n occurrences option is enabled.
• A user accepts the recurring meeting request in Microsoft Outlook Web Access.

Note The problem does not affect the appearance of the meeting request in Outlook Web Access.

This problem occurs because the patternend property is calculated incorrectly when a meeting request is accepted in Outlook Web Access.

To work around this problem, modify the WebDAV application to calculate the pattern end date based on the start date information. Then, set the number of occurrences.

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