Users may receive duplicate calendar items for the updated instance on mobile devices
This article has been archived. It is offered "as is" and will no longer be updated.
Consider the following scenario:
- A Microsoft Exchange Server 2007 user uses Exchange ActiveSync to synchronize calendar items on a mobile device.
- The Direct Push feature is enabled for the synchronization.
- This user accepts a recurring meeting request, and the recurring meeting is synchronized to the mobile device.
- This user accepts an update to an instance of this recurring meeting on the mobile devices.
In this scenario, the user may obtain duplicate calendar items for the updated instance on the mobile device, and these duplicate calendar items cause conflicts and are confusing to the user.
Note By default, the Direct Push feature is enabled on a Windows Mobile 5.0 device that has the Messaging and Security Feature Pack (MSFP) installed or on a Windows Mobile 6.x device (Windows Mobile 6.x devices do not use the Messaging and Security Feature Pack).
Exchange ActiveSync offers Direct Push technology. Direct Push uses an encrypted HTTPS connection that is established and maintained between the device and the server to push new e-mail messages and other Exchange data to the device. During the response processing of a recurring meeting request, a wrong meeting ID is used that causes unwanted duplication.
To resolve this problem, install Update Rollup 8 for Exchange Server 2007 Service Pack 1.
