Reading the list of PST files from the registry

[Israel Sadeh]

Hi All,
How do I read the list of PST files belonging to an outlook profile, from the registry?
I know that all profiles are listed in the registry under:

HKEY_CURRENT_USERSoftwareMicrosoftWindows NTCurrentVersionWindows Messaging SubsystemProfiles

further more, I know that the PST path can be retrieved from the keys 001e6700 (ANSI name) or 001F6700 (Unicode name).

However, I found out that those keys remain in the registry even after a PST file is removed from the profile.

How can I detect whether the PST file was removed from the profile?

Thanks in advance
