How to Reset Outlook 2016 / 2013 / 2010 to First Run State for Clean & Fresh Profile

Use the following trick to reset Outlook so that the default ‘Outlook’ profile is deleted and first run wizard is offered again to set up a new default ‘Outlook’ profile.

1. Exit Outlook completely (make sure outlook.exe is not running in Task Manager).
2. Open Command Prompt as Administrator from user account who is using the Outlook.
3. Run the following command:
   
   For Outlook 2010 or Earlier:
   

   reg.exe delete HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\Outlook /f
   reg.exe add HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\Outlook

   
   For Outlook 2013:
   

   reg.exe delete HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\Profiles\Outlook /f
   reg.exe add HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\Profiles\Outlook

   
   For Outlook 2016:
   

   reg.exe delete HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Profiles\Outlook /f
   reg.exe add HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Profiles\Outlook

   For other newer version of Outlook, just change the version number, i.e. 15.0, 16.0, to new version accordingly. In addition, the default profile name, Outlook, may not be the same across all versions of Outlook, so it’s recommended to browse the registry key to confirm the name of the profile used.

    The commands delete the default profile called Outlook located in HKCU\Software\Microsoft\Office\15.0\Outlook\Profiles registry key, and then recreate it with no settings.
   
4. Run Outlook again, it should open the first run wizard.
