Troubleshoot dragging and dropping items

I dragged multiple items, but now I only see one new item.

When you drag multiple items simultaneously into a Microsoft Outlook folder or shortcut, all the information is placed in one new item. For example, if you drag three e-mail messages simultaneously to the Calendar folder, you will see the text of all three messages in the body of the new appointment. If you want to create new appointments for each of the three messages, drag each message separately.
