Outlook can automatically translate messages you receive in another language. Turn on this feature in Message handling settings or when you receive a translation suggestion.
To enable this feature by default, access your mailbox Settings using the Gear button and then click on the View all Outlook settings link available at the bottom.
Then access the General\Message handling section and locate the Translation section; you can then disable the translation service or define a list of language for which the message will not be translated
Then when you will received an email in a different language, depending of these settings you will be asked to translate it or it will not be translated.
