Exchange server – cannot get sender email address using EWS Java API

I am using EWS Java API 1.1 5. I am trying to get the email sender as follows:

ItemView view = new ItemView(10);
FindItemsResults<Item> findResults = service.findItems(
    WellKNownFolderName.In@R_969_2419@,view);
    for (Item item : findResults.getItems()) {
        if (item instanceof EmailMessage) {
            String senderEmail = ((EmailMessage) item).getSender().getAddress();
            System.out.println("Sender Email: " + senderEmail);
        }
    }
);

But it always returns null I have also tried the following:

String senderEmail = ((EmailMessage) item).getFrom().getAddress();

But it also returns null I can see that the email contains the sender:

Test User <testuser@testdomain.com>

It appears in messages, and so does when replying to emails

Please show me how to solve this problem

Solution

To find a solution, I must use item load(); Before receiving the sender's e-mail address
