        ExecuteMultipleRequest request = new ExecuteMultipleRequest()
        {
            Settings = new ExecuteMultipleSettings()
            {
                ContinueOnError = true,
                ReturnResponses = true
            },
            Requests = new OrganizationRequestCollection()
        };

        for (int i = 0; i < entities.Count; i++)
        {
            request.Requests.Add(new UpdateRequest() { Target = entities[i] });
        }

        return (ExecuteMultipleResponse) ServiceContext.Execute(request);
    }
