In Depth Information
A native, or default, application is an application that is registered on your system for working with
a particular kind of file. For some kinds of files there is only one application that can be “native,”
such as Microsoft Word for Word files and Excel for Excel files. For other kinds of files, such as image
files, there are many possibilities and it will depend on what’s installed on your system. For example,
on my system PhotoShop is registered as the native application for most image files, but on your
system it might be Paint Shop Pro or Corel Draw.
Opening an attachment in its native application is usually done by saving the attachment to disk, as
described earlier, and then starting the application and opening the file as usual. You can, however,
open an attachment directly from Outlook by following these steps:
Open the message or display it in the reading pane.
Right-click the attachment name.
Select Open from the context menu.
Depending on the file type, Outlook may display a warning dialog box asking whether
you want to open or save the file. Click Open.
The attachment will be opened in its native application.
The reason for the cautionary dialog box in step 3 is security. Some kinds of files, such as Word
documents and Excel workbooks, have the potential to contain malicious macro code that could
harm your system. This code is harmless unless the file is opened, so you may want to save it to
disk first and run a virus scan before opening it.
If you do open an attachment this way, you can work with it in the application as you normally
would, including saving to disk.
Understanding the Inbox Display
The Inbox, or any other Outlook folder that contains email messages, provides you with a lot of
information about the messages it contains. The display is arranged in columns, or fields, with
each field identified at the top of the display. You can customize this display by adding, removing,
and rearranging columns. That topic is discussed in Chapter 19. For now it’s important for you to
understand the meaning of the fields in the default Inbox display. They are, from left to right in the
default display (see Figure 4.12), as follows:
