Attachments are a widely used feature of Outlook because they are a common way for people to send and receive files. It's easy to send a file as an attachment by using the keyboard, as you can see in the illustration on the left.
To send another e-mail message as an attachment, use the Item command (press E) on the Insert menu (ALT+I).
Note If you are using Microsoft Word as your mail editor and you want to add another message as an attachment, you have to use the Insert File button . The exact details of how to do this are in the Quick Reference Card.
Reading an attachment is not the easiest thing to do using keystrokes. The best practice is to open the attachment from a closed message. In a folder, select the message which has the attachment, press SHIFT+F10, select View Attachments by pressing H, use the arrow keys to select the required attachment (there could be more than one), and then press ENTER to open the attachment.
If you want to open an attachment from within a message, it's a bit more complicated. How you see an attachment in a message depends on the message format, whether it's Plain Text, RTF (Rich Text Format), or HTML (Hypertext Markup Language).
Read an attachment in an RTF message The attachment appears in the body of the message. Move to the attachment by using the arrow keys, select it by using SHIFT+LEFT ARROW or SHIFT+RIGHT ARROW, press SHIFT+F10 to open the shortcut menu, and then select Open by pressing O.
Read an attachment in a Plain Text or HTML message From the open message, press SHIFT+TAB to move into the attachment area of the message header, select the attachment with SHIFT+LEFT ARROW, press SHIFT+F10 to display the shortcut menu, and then type O for Open.
Save an attachment From the open message, use the Save Attachments command (press N) on the File menu (ALT+F).
