SYMPTOMS
When you try to make a programmatic change to the value of the message-ID field of an e-mail message, you are not successful.



CAUSE
This problem occurs because the Collaboration Data Objects (CDO) component (Cdosys.dll) contains code that prevents client code from changing the value of the message-ID field.

The following Microsoft Visual Basic Scripting Edition script is an example of the client code that prevents the change: sID = &quot;440212-1-1922589443@contoso.com&quot;

set m = CreateObject(&quot;CDO.message&quot;)

with m.fields

.item(&quot;urn:schemas:mailheader:message-id&quot;) = sID

.update

end with

m.send

wscript.echo sID & &quot; :: &quot; & m.fields.item(&quot;urn:schemas:mailheader:message-id&quot;)
