Missing or corrupted files cause the body of an e-mail message to be a gray box that has a red X in the upper-left corner in Exchange Server 2003

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.

This problem occurs if the registration of the following files is missing or corrupted on the computer on which the problem occurs:

• C:\Program Files\Common Files\Microsoft Shared\Triedit\triedit.dll
• C:\Program Files\Common Files\Microsoft Shared\Triedit\dhtmled.ocx

To resolve this problem, use a command prompt to reregister the affected files on the computer on which the problem occurs. To do this, follow these steps:

1. Click Start, click Run, type CMD in the Open box, and then click OK.
2. At a command prompt, type the following command, and then press ENTER after each command:
   regsvr32 "C:\Program Files\Common Files\Microsoft Shared\Triedit\triedit.dll"
   regsvr32 "C:\Program Files\Common Files\Microsoft Shared\Triedit\dhtmled.ocx"
3. Close the command prompt.
