Recurring events in Calendar over DST are not adjusted on all ActiveSync devices in all Exchange Server environments

Applies to: Exchange Server 2013 EnterpriseExchange Server 2013 Standard EditionExchange Server 2010 Service Pack 3


Assume that you create recurring meetings in Calendar in a Microsoft Exchange Server environment. In case the Time Zone settings for meeting TimeZone are changed, all meetings over Time Zone changes dates are automatically adjusted as expected in Microsoft Outlook, Outlook Web App, or Outlook Web Access.

This issue occurs because the value of the PidLidAppointmentTimeZoneDefinitionRecur property that stores the Time Zone definition is sent and stored in the mailbox without adjustment when recurring meetings are sent to ActiveSync devices. At the same time, Outlook Web App or Outlook can automatically adjust the property.


To resolve this issue in Exchange Server 2013 or Exchange Server 2010, install one of the following updates:
