how to (re)set the default data file for Outlook in a VB program

[ron podl]

I want to be able to (re)set the default data file for Outlook 2007 in a VB
program (using Visual Studio 2008).
I would like to recognize which Store is the "default data file" and switch
the default to different file.
I'm assuming that, as the Outlook dialogs do, you can't remove the default
store until a new default is set.
See rough program outline.

For Each s as Store In outlookNS.Stores
dim NewName as String = appdata & "\" & Path.GetFileName(s.FilePath)
copy the original Store file to a new location (NewName)
outlookNS.AddStore(NewName)
if s.? is default data file then ' how can I find if it is the default?
find the store just added
make it the default data file ' how to set it?
end if
outlookNS.RemoveStore(s.GetRootFolder)
Next

I don't know any way to do what you want using the Outlook object model.
Maybe using Extended MAPI and C++ or Delphi, but definitely not with VB and
the Outlook object model. My guess, which Dmitry can confirm, is that you'd
need to work with the IProfAdmin interfaces.

Thanks.
I did find this, http://msdn.microsoft.com/en-us/library/bb176395.aspx, this
morning, which talks about getting & setting properties not explicity exposed
in the outlook object model. Doesn't seem to be much information about the
available SchemaNames/namespaces for any of the non-item objects:
AddressEntry, AddressList, Attachment, ExchangeDistributionList,
ExchangeUser, Folder, Recipient, and Store.
