            When the test starts, a RED panel appears.
            1. Start MS Outlook program. Find and open the mail form with attachments.

            2. Select attachments from the mail and drag into a red field of the window.
                When the mouse enters the field during the process of drag, the application
                should change the cursor form to OLE-copy and field color to yellow.

            3. Release the mouse button (drop attachments) over the field.
                File paths in temporary folder should appear.
                You should be able to repeat this operation multiple times.

            If the above is the case then press PASS, else FAIL.
