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 Outlook folder and select Export…save it anywhere you want…and run it while restoring your outlook. Afterwards, close RegEdit.
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.
