Consider the following scenario. You use Microsoft Outlook Web Access from one computer to access your mailbox. Your mailbox is running in a Microsoft Exchange Server 2003 environment. Then, you try to perform one of the following tasks:

•	Send a new e-mail message from your mailbox.
•	Reply to an existing e-mail message from your mailbox.

In this scenario, the body of the new e-mail message or of the reply to e-mail message is a gray box. Additionally, there is a red X in the upper- left corner of the gray box.

However, when you try to use Outlook Web Access to complete the same tasks on a second computer, the tasks can be completed as expected.
