Microsoft has implemented changes to its writing assistance tools within the Microsoft 365 suite. In early September 2026, the company announced it would disable default text predictions in Word and Outlook, moving from an opt-out to an opt-in model. The company stated this change aims to “provide a more consistent and user-controlled writing experience” and minimize “unwanted interruptions.” Following this adjustment to user control, Microsoft announced plans to introduce a native spell-check feature for the New Outlook for Windows and Outlook on the web. This feature will scan messages for spelling and grammatical errors immediately before a user clicks the send button, acting as a “final safety net” to prevent typos in outgoing communications. ~~The feature will be an optional setting that~~ According to Microsoft’s 365 Message Center, the functionality, titled “Spell check before sending emails in the new Outlook,” allows users ~~must manually activate.
