We are an international company with international clients but in various countries we offer localized versions of Office and Outlook to our employees.

A downside of this is that when replying or forwarding, Outlook also adds localized prefixes to the subjects such as “AW” and “WG” (for the German version) which causes confusion with the recipient as they may not be German themselves.

Is there a way to force Outlook to always use the more standard English “RE” and FW” prefixes?
