When a language change is made from English to a foreign language, you might end up with a message header in that language.
Microsoft Outlook is set to default the From, To, CC, Send, BCC, subject, attachment boxes in English for messages, replies, etc.
If your message header appears in a language other than English, change the settings.
Open the Outlook program
Make sure all the boxes are checked off.
