In new Outlook for Windows, spelling, grammar, and style suggestions (including right‑click correction menus) are provided by Microsoft Editor. Editor works fully when composing in formats that support its features (such as HTML). In plain text compose, only basic indication of misspelled words (red underlines) is available; the richer Editor suggestion experience, including right‑click correction lists, is not provided.
To get right‑click spelling suggestions, compose the message in HTML (or another supported format) so that Editor can fully function:
- Start a new email in new Outlook.
- Ensure the message is composed in a format that supports Editor (for example, HTML).
- On the Message tab, in the Options group, select Editor to open the Editor pane and review categorized spelling and grammar issues.
- Use the underlines and Editor pane to apply corrections.
If composing must remain in plain text, use the red underlines as indicators and manually correct the text, or temporarily switch to HTML to use Editor suggestions, then convert the content back to plain text before sending.
