SYMPTOMS

In a Microsoft Exchange Server organization, a Microsoft Entourage user may receive a meeting request that does not correspond to the meeting time that is specified by the meeting organizer.

Additionally, the user receives the following confusing message:
Event and computer time zones do not match. In Calendar views, the event is adjusted to display correctly.
Additionally, the Entourage user finds that the start time and the end time that are displayed in the opened meeting request differ from the start time and the end time that are displayed in the table view of the calendar.

This problem occurs if the following conditions are true:
  • The Microsoft Outlook client computer from which the meeting request originated and the target Entourage client computer are in the same time zone. However, the Exchange Server computer is in a different time zone.
  • The meeting organizer uses Outlook to send a single-instance meeting request to the Entourage user.

CAUSE

This problem occurs because the following sequence of events occurs:
  • For single-instance meeting requests, Outlook stamps the time field in the request by using Coordinated Universal Time (UTC). However, Outlook does not include any time zone information.
  • When Exchange Server converts the MAPI format to iCal format, Exchange Server stamps the time field by using the local time on the server.
Therefore, when the Entourage client computer receives the meeting request, the time is incorrect.
