Recurring appointments in the calendar public folder are not replicated correctly in Microsoft Exchange Server 2007

You create a public folder as a calendar item in Microsoft Outlook and then create appointments in it. However, changes that are made to recurring calendar appointments in the public folder are not replicated correctly in Microsoft Exchange Server 2007.

Consider the following scenario. A recurring appointment is created on one public folder server. This item is replicated correctly to another public folder server. Then, the organizer makes changes to these recurring appointments. However, these changes are not replicated correctly to other public folder servers. Therefore, users still receive the original versions of the appointments. When this problem occurs, the following event error is listed in the event log:

Event Type: Warning
Event Source: MSExchangeIS Public Store
Event Category: Replication Errors
Event ID: 3085
Description:
Error 1129 occurred while generating an outgoing replication message. Type: 0x80000004 Folder: (<FID>) <Public Folder name> Database "<Storage Group>/<Public Store>".

Changes to recurring appointments are processed as exceptions. In this scenario, the exceptions were ignored when the public folder was replicated.

To resolve this problem, install the following update rollup:
