Start Outlook in Safe Mode without any extensions

Modified on Thu, 23 Mar, 2023 at 11:00 PM

Starting Outlook in Safe Mode actually means that it will be run without any add-ins that are currently installed on your machine. It is the fastest way to determine if the problem on Outlook start up is caused by some of the add-ins.

To open Outlook in safe mode, click on its icon holding the Ctrl key, or click paste outlook /safe in the search box and press Enter. Outlook will display a message asking you to confirm that you really want to start it in safe mode, click Yes.

An alternative way is to use the outlook.exe /noextensions command, which basically means the same - start Outlook without any extensions.


When you are using Outlook 2016, Outlook 2019 or Microsoft 365, then you can also open the Mail Setup dialog with the /managemailprofiles switch.

  • Start-> type; outlook.exe /manageprofiles
