I knew there was a registry key for this but it wasn’t so easy to find….

after digging the net / google for more than 30 minutes, I finally found the way to do it…

Just locate the following key in registry (start – run – regedit):

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\Outlook

Then right click on the key, outlook and select option, Export…save it anywhere you want…

and run it while restoring your outlook.

This will restore your old outlook profile with all email accounts and rules.

But, you will have to enter passwords for the accounts again. It does not store the user passwords.
