When you receive an e-mail message that contains animated graphics, such as animated .gif files, only a static image appears.
Microsoft Office Outlook 2007 does not display animated graphics files in the body of e-mail messages. Only the first frame of the animation appears.
You can view the message in your Web browser to see the animation.
