egistry key to find pst locations?

The PST file locations are stored in the profile sections in the registry. The officially supported API designed to access and manipulate the profile data is the IProfAdmin interface (you can play with it in OutlookSpy if you click the IProfAdmin button). PST path is stored in the PR_PST_PATH property. Extended MAPI can only be accessed from C++ or Delphi.

You can use ProfMan (it comes with the distributable version of Redemption); ProfMan can be used from any language. The following script (VB) retrieves PST files names from all local profiles:

'Print the path to all the PST files in all profiles
 PR_PST_PATH = &H6700001E

 set Profiles=CreateObject("ProfMan.Profiles")
 for i = 1 to Profiles.Count
   set Profile = Profiles.Item(i)
   set Services = Profile.Services
   Debug.Print "------ Profile: " & Profile.Name & " ------"
   for j = 1 to Services.Count
     set Service = Services.Item(j)
     If (Service.ServiceName = "MSPST MS") or (Service.ServiceName = "MSUPST MS") Then
      MsgBox Service.Providers.Item(1).ProfSect.Item(PR_PST_PATH)
     End If
   next
 next

You can also retrieve PST file names from PST stores using the Outlook Object Model (but that requires Outlook to be running, and you can only do that for the currently used profile) - use the Store.FilePath property:

set vApp = CreateObject("Outlook.Application")
for each vStore in vApp.Session.Stores
  MsgBox vStore.DisplayName & " - " & vStore.FilePath
next
