"GetUserOofSettings", "SetUserOofSettings" and "GetUserAvailability" operations do not support Exchange Impersonation on the Exchange Server 2010 SP1 schema

Symptoms

You try to auto-generate proxy code based on the Microsoft Exchange Server 2010 Service Pack 1 (SP1) schema. In this situation, the following line is missing in the proxy code:
[System.Web.Services.Protocols.SoapHeaderAttribute("ExchangeImpersonation")] 
Therefore, the auto-generated proxies do not support Exchange Impersonation.

This issue affects the following three operations:
  • GetUserOofSettings
  • SetUserOofSettings
  • GetUserAvailability

Resolution

To resolve this issue, install the following update rollup:
2579150 Description of Update Rollup 4 for Exchange Server 2010 Service Pack 1

Workaround

To work around this issue, use Microsoft Exchange Web Services (EWS) Managed API 1.1 to change the generated classes in the schema. To do this, add the following line in the proxy code:
[System.Web.Services.Protocols.SoapHeaderAttribute("ExchangeImpersonation")] 
Below is a sample for the GetUserOofSettings operation.

Original code:
[System.Web.Services.Protocols.SoapHeaderAttribute("ServerVersionInfoValue", Direction = System.Web.Services.Protocols.SoapHeaderDirection.Out)]
[System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://schemas.microsoft.com/exchange/services/2006/messages/GetUserOofSettings", Use = System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle = System.Web.Services.Protocols.SoapParameterStyle.Bare)]
[return: System.Xml.Serialization.XmlElementAttribute("GetUserOofSettingsResponse", Namespace = "http://schemas.microsoft.com/exchange/services/2006/messages")]
public GetUserOofSettingsResponse GetUserOofSettings([System.Xml.Serialization.XmlElementAttribute(Namespace = "http://schemas.microsoft.com/exchange/services/2006/messages")] GetUserOofSettingsRequest GetUserOofSettingsRequest)
{
object[] results = this.Invoke("GetUserOofSettings", new object[] {
GetUserOofSettingsRequest});
return ((GetUserOofSettingsResponse)(results[0]));
}
Changed code:
[System.Web.Services.Protocols.SoapHeaderAttribute("ServerVersionInfoValue", Direction = System.Web.Services.Protocols.SoapHeaderDirection.Out)]
[System.Web.Services.Protocols.SoapHeaderAttribute("ExchangeImpersonation")]
[System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://schemas.microsoft.com/exchange/services/2006/messages/GetUserOofSettings", Use = System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle = System.Web.Services.Protocols.SoapParameterStyle.Bare)]
[return: System.Xml.Serialization.XmlElementAttribute("GetUserOofSettingsResponse", Namespace = "http://schemas.microsoft.com/exchange/services/2006/messages")]
public GetUserOofSettingsResponse GetUserOofSettings([System.Xml.Serialization.XmlElementAttribute(Namespace = "http://schemas.microsoft.com/exchange/services/2006/messages")] GetUserOofSettingsRequest GetUserOofSettingsRequest)
{
object[] results = this.Invoke("GetUserOofSettings", new object[] {
GetUserOofSettingsRequest});
return ((GetUserOofSettingsResponse)(results[0]));
}
