I originally posted this on 2/15 but never got any responses so I'm trying again. We have a client who recently upgraded to Exchange 2007, ever since that was done they're reporting that when they request delivery confirmation from external email addresses, the confirmation arrives in Korean. I took a look, and sure enough the delivery confirmation appears to be in some foreign language. The read receipt appears fine however. The strange thing is that if you view the same delivery confirmation via OWA, it appears in English. When looking at it using the Outlook client (XP) and clicking the Forward button, it turns back into English as well. I looked at the language settings both in Outlook and in the Control Panel and I don't see anything there that would cause this behavior. Anyone have any idea what might be causing this? -Keith
