Exchange 2010 and Application Impersonation Issue

I am trying to setup Application Impersonation in Exchange 2010 to allow a .NET application the ability to read/update my organization's calendars.

So far, I have created a service account and a Role Assignment

New-ManagementRoleAssignment -Name:myServiceCalendar -Role:ApplicationImpersonation -User:myService

However, when I go to actually access the calendar of an account, I get an ErrorFolderNotFound

Here is the code that I am using for the test

        var _testUserName = "[email protected]";
        var _testUser = new WebCredentials(_testUserName, "Apass@wordForYou");

        var service = new ExchangeService(ExchangeVersion.Exchange2010_SP1);

        service.Credentials = _testUser;

        service.TraceEnabled = true;
        service.TraceFlags = TraceFlags.All;

        service.AutodiscoverUrl(_testUserName);

        var testCalendar = new Mailbox("[email protected]");
        var folderCalendar = Folder.Bind(service, new FolderId(WellKnownFolderName.Calendar, testCalendar)); // <-- FAILS HERE

        var view = folderCalendar.FindItems(new ItemView(10));

Here is the error that I am getting

<Trace Tag="EwsResponse" Tid="10" Time="2015-08-07 19:26:11Z" Version="15.00.0847.030">

        <m:ResponseMessages>
          <m:GetFolderResponseMessage ResponseClass="Error">
            <m:MessageText>The specified folder could not be found in the store.</m:MessageText>
            <m:ResponseCode>ErrorFolderNotFound</m:ResponseCode>
            <m:DescriptiveLinkKey>0</m:DescriptiveLinkKey>
            <m:Folders />
          </m:GetFolderResponseMessage>
        </m:ResponseMessages>
      </m:GetFolderResponse>
    </s:Body>
  </s:Envelope>
</Trace>

Here is the account I am trying to access enter image description here

So my question is -- what am I missing? Did I setup the Role assignment incorrectly? Or do I need to do something different in the code?

In the Exchange Service object there is an ImpersonatedUserId property that needs to be set. See this.
