Do you often include multiple translations in a single email message? If so, a great time saver is to have Outlook for Mac detect and spell check those translations for you automatically.

It's a two-step process. First, select the languages you use most often. Next, compose your message.

Choose the preferred language

  1. On the Mac, select System Preferences (System Preferences button on Mac) > Language & Region (Language and Region button on Mac).

  2. Under Preferred languages, select +.

  3. Select the language you plan to use > Add.

  4. Select the primary language.

  5. Repeat for each language.

Compose your email message

  1. If Outlook is open, exit and restart it so the language additions can take effect.

  2. Open a new email message, place the cursor in the body of the message, and select Edit > Language > Language.

  3. Select Detect language automatically > OK. Outlook will remember this setting so you won't need to set it again.

    Tip: Language detection works on full sentences only. Be sure to end your sentences with punctuation to trigger language detection.
