Starting Outlook in safe mode can be useful when you're experiencing problems such as add-in conflicts or startup issues. To do so, close Outlook if it's already open, then press and hold the "Ctrl" key while clicking on the Outlook shortcut to open it. A prompt will appear asking if you want to start Outlook email in safe mode. Click "Yes" to confirm, and Outlook will launch with limited functionality and no add-ins.
