This article describes a feature that lets users configure Outlook to read all non-digitally-signed e-mail messages or nonencrypted e-mail messages in plain text format. This feature was added to Outlook 2002 in Microsoft Office XP Service Pack 1 (SP1). This feature also allows system administrators to configure policies that require users to read all non-digitally-signed e-mail messages or nonencrypted e-mail messages in plain text only.
Note Digitally signed e-mail messages or encrypted e-mail messages are not affected by this update and cannot be changed by a system policy. Digitally signed e-mail messages or encrypted e-mail messages are read in their original formats.

To turn on the "Read as Plain Text" feature, follow these steps:
On the Edit menu, point to New, and then click DWord Value.
With the new Dword value selected, type ReadAsPlain.
Double-click the new value to open it.
In the Value Data box, type 1, and then click OK two times.
Exit Registry Editor.
Note When you programmatically work with existing messages, if the "Read as Plain Text" feature is turned on, the BodyFormat property returns a value of olFormatPlain. When the "Read as Plain Text" feature is turned on, this value cannot be changed. This is true even though Help states that the BodyFormat property is read/write. If you try to set the BodyFormat property to any other value, you receive the following error message:
Error 80070057 "Could not complete the operation. One or more parameter values are not valid."
After you turn on the "Read as Plain Text" feature, users notice the following changes:
The changes are applied to the preview pane and open messages.
Pictures become attachments to avoid loss.
The object model (custom code solutions) may behave unpredictably because the message is still in Rich Text or HTML format in the mail store.
Digitally signed messages are not affected.
