Starting in March 2025, Outlook will introduce a setting to hide Copilot entry points, configurable per account and syncing across all Outlook applications. This applies to both organizational and personal accounts. Classic Outlook for Windows will not have this setting, but changes will sync with it. Admins should inform users.
Applies to: Exchange Online · Microsoft 365 for the web · Microsoft 365 apps
