A family of Microsoft word processing software products for creating web, email, and print documents.
Thanks for clarifying.
In Outlook web, start a new email, then select:
- Three dots (…) on the message toolbar > Editor > Editor Settings
- Turn Autocorrect off. You can leave the spelling suggestions enabled. Outlook on the web provides an AutoCorrect toggle rather than the same custom replacement list available in Classic Outlook.
- After turning it off, try typing Higer again.
If it still changes to Higher, the correction may be coming from your web browser instead of Outlook. Which browser are you using? Also, does the same correction happen when typing Higer in another website’s text box?
