ConflictResolutionType Enumeration

The ConflictResolutionType enumeration specifies how a conflict is handled during an UpdateItem operation.

Namespace:  ExchangeWebServices
Assembly:  EWS (in EWS.dll)

public enum ConflictResolutionType

Member nameDescription
NeverOverwriteIf conflict exists, the UpdateItem operation fails and an error is returned.
AutoResolveThe UpdateItem operation automatically resolves any conflict. The AutoResolve option will in most cases overwrite the existing value for a property. In some cases, the new value is ignored and the original value is retained. For example, user A changes the Sensitivity property from Normal to Confidential. Then user B sets the value to Public. In this example, the Confidential setting is retained and user B's update is ignored.
AlwaysOverwriteIf there is a conflict, the UpdateItem operation will overwrite information.

This enumeration is used by the ConflictResolution property of the UpdateItemType object. A conflict occurs when a client tries to update a property that has already been set.
