Associated properties:
Property type:


The types of standard Microsoft Outlook items that support automatic conflict resolution include the following standard item types: appointment items, contact items, journal items, mail items, meeting items, sticky note items, and task items. An item belonging to a message class that derives from one of these standard item types also supports automatic conflict resolution. In Microsoft Outlook 2003 and Microsoft Office Outlook 2007, when Outlook synchronizes items and considers that there is a possibility that the resultant copy may not contain all essential data, Outlook stores the conflicting copies in the Conflicts folder, under the Sync Issues folder.


Sync Issues and its subfolders are hidden until you click Folder List on the Go menu.

An item exposes the PR_CONFLICT_ITEMS property if it is one of the item types that support automatic conflict resolution, has won in a conflict resolution, or was placed in the Conflicts folder because of a conflict resolution. The folder in which the item is placed determines the content of PR_CONFLICT_ITEMS. If the item is located in some folder other than the Conflicts folder, and the item exposes the PR_CONFLICT_ITEMS property, the item must have won the conflict resolution, and PR_CONFLICT_ITEMS would contain one or more entry IDs of those items that lost in the conflict resolution. If the item is located in the Conflicts folder and the item exposes the PR_CONFLICT_ITEMS property, this item must have lost the conflict resolution, and PR_CONFLICT_ITEMS would contain the entry ID of the item that won in the conflict resolution.
