Question

In Outlook 2007, I am able to loop through mails stores, including PSTs, using code like this:

Dim stores As Outlook.stores
Set stores = objNamespace.stores
Dim store As Outlook.store

For Each store In stores
    MsgBox store.FilePath
Next

However, in Outlook 2003, the Outlook.store and Outlook.stores objects do not exist.

Are there equivalent objects in Outlook 2003?
What other method might I use to loop through mail stores?

Thank you.

This sample code for Outlook 2003 will loop through the high level mailboxes and print certain properties to the Immediate Window. I chose the properties that looked most useful based on your request.

Sub LoopThruMailboxes()

Dim olApp As Outlook.Application
Dim olNS As Outlook.NameSpace
Dim mailboxCount As Long
Dim i As Long
Dim folder As Outlook.MAPIFolder

' get local namespace
Set olApp = Outlook.Application
Set olNS = olApp.GetNamespace("MAPI")

mailboxCount = olNS.Folders.count

For i = 1 To mailboxCount
  Set folder = olNS.Folders(i)

  Debug.Print folder.EntryID
  Debug.Print folder.StoreID
  Debug.Print folder.Name
  Debug.Print folder.FolderPath
Next i

End Sub

folder.Name is the name of the mailbox, folder.StoreID is the store ID (I’m not sure what you meant by “store file path”, I didn’t see anything that looked relevant anyway).

Here’s a functionized version that returns folder name and store ID as an array, which you could assign directly to a listbox:

Function GetMailBoxInfo() As String()

Dim olApp As Outlook.Application
Dim olNS As Outlook.NameSpace
Dim mailboxCount As Long
Dim i As Long
Dim folder As Outlook.MAPIFolder
Dim tempString() As String

' get local namespace
Set olApp = Outlook.Application
Set olNS = olApp.GetNamespace("MAPI")

mailboxCount = olNS.Folders.count

' size array accordingly
ReDim tempString(1 To mailboxCount, 1 To 2)

For i = 1 To mailboxCount
  Set folder = olNS.Folders(i)

  tempString(i, 1) = folder.Name
  tempString(i, 2) = folder.StoreID
Next i

  GetMailBoxInfo = tempString

End Function

ex:

ListBox1.List = GetMailBoxInfo
