Question

I’m trying to access my email using EWS. It is working fine from a Console application. But when I’m trying to access same piece of code using WCF service it is giving me error:

When making a request as an account that does not have a mailbox, you must specify the mailbox primary SMTP address for any distinguished folder Ids

Here is my code :

        ExchangeService service = new ExchangeService();
        service.Credentials = new WebCredentials("username", "password");
        service.TraceEnabled = true;
        service.AutodiscoverUrl("emailID");

        FindItemsResults<Item> findResults = service.FindItems(
        WellKnownFolderName.Inbox,
        new ItemView(10));

Any help will be greatly appreciated

Edit 1: I’m calling this WCF service from a WP7 app and here is the ServiceReferences.ClientConfig setting

    <system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding name="BasicHttpBinding_ITestService" maxBufferSize="2147483647"
                maxReceivedMessageSize="2147483647">
                <security mode="None" />
            </binding>
        </basicHttpBinding>
    </bindings>
    <client>
        <endpoint address="http://MachineIP/Service1.svc" binding="basicHttpBinding"
            bindingConfiguration="BasicHttpBinding_ITestService" contract="ServiceReference1.ITestService"
            name="BasicHttpBinding_ITestService" />
    </client>
</system.serviceModel>

In my service method I disable Impersonation and it got fixed

[OperationBehavior(Impersonation = ImpersonationOption.NotAllowed)]
