257824 OL2000: Differences Between Outlook and Outlook Express



SYMPTOMS
When you open an e-mail or news message with Outlook Express or Outlook, images in the message may not be displayed. An image may appear as a box with a red X in it.



CAUSE
This behavior can occur if the message was sent using CMYK color format. The CMYK format uses the four process colors (cyan, magenta, yellow, and black) used in four-color printed reproduction.



RESOLUTION
To resolve this issue, the sender should send the message using RGB color format. The RGB format uses the primary colors in color video (red, green, and blue).



MORE INFORMATION
Typically, images are encoded in a three-channel RGB format. It is possible, in some programs, to create images that are encoded in four-channel CMYK color format. Windows is unable to display images that are not in three-channel RGB color format.
