How to Start Outlook in Safe Mode?

Microsoft Office applications (like Windows OS), have a special launch mode – Safe mode, which allows to run the desired application in a minimal configuration when it stops running in normal mode.

So, if you start Outlook and there are some critical errors occurred (they prevent its normal launch), Outlook will automatically start in a Safe mode. When you start Microsoft Office in a safe mode, it runs without any add-ins and extensions. In this mode you can’t save template settings, preferences and new tags, also you can’t perform any ribbon customization or create/open documents with restricted permissions.

When working in Safe Mode, you can disable any additional or third-parties extension that preventing normal Outlook functionality (File -> Add-ins -> COM Add-ins -> Go -> Clear all COM add-in checkboxes).

Tip. There is a reverse situation. In some cases MS Outlook 2010 constantly starts only in a safe mode. In this case, it’s recommended to create a key that prohibits the use of a safe mode. To do this follow the steps below:

  1. Open regedit.exe and go to the branch HKEY_LOCAL_MACHINE\Software\Microsoft\Office\14.0\Outlook\Security\
  2. Create DWORD key with the name DisableSafeMode and value 1
