A new Microsoft Editor feature aims to make OWA messages more polite through "tone detection. Currently only available for U.S. English, Editor scans for impolite text and comes up with suggested replacement text. The results vary from very good to not so good, but this might be because it takes time for a learning model to accumulate enough information about a user’s writing style to be able to detect impolite text accurately. We’ll know over time.
