Outlook Folders don't GetNext

Hi,
I want to display the outlookfolders into a treeview.
So far I got this,
but the GetNext doesn't work and here it stays on Inbox...
The Treeview is 'T'

VB Code:

Private Sub OutlookFolders_Load()
        Dim OutlApp As Outlook.Application
        Dim oNS As Outlook.NameSpace
        Dim oFolder As Outlook.MAPIFolder
 
        OutlApp = CreateObject("Outlook.Application")
        oNS = OutlApp.GetNamespace("MAPI")
        oFolder = oNS.Folders.GetFirst
 
        Dim tn As TreeNode
        Do While Not oFolder Is Nothing
            tn = New TreeNode
            tn.Text = oFolder.Name
            T.Nodes.Add(tn)
            If Not oFolder.Folders.Count = 0 Then GetFolders(oFolder, tn)
            oFolder = oNS.Folders.GetNext
        Loop
 
    End Sub
    Private Sub GetFolders(ByVal F As Outlook.MAPIFolder, ByVal HN As TreeNode)
        Dim tn As TreeNode
        Dim oFolder As Outlook.MAPIFolder = F.Folders.GetFirst
 
        Dim i As Integer
        oFolder = F.Folders.GetFirst
        For i = 0 To F.Folders.Count - 1
            tn = New TreeNode
            tn.Text = oFolder.Name
            HN.Nodes.Add(tn)
            GetFolders(oFolder, tn)
            oFolder = F.Folders.GetNext
        Next
 
    End Sub

And I just want the folders.
I didn't thought it was so hard...

T is the treeView...

VB Code:

Private m as Integer 'for the tag in the treenodes; 0 is the first nodes, 1 the second etc.
 
Private Sub FormOutlookFolders_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim OutlApp As Outlook.Application
        Dim oNS As Outlook.NameSpace
        Dim oFolder As Outlook.MAPIFolder
        Dim InFolder As Outlook.Folders
 
        Dim FirstFolder As Outlook.Folders
        Dim FirstFolder2 As Outlook.Folders
 
        OutlApp = CreateObject("Outlook.Application")
        oNS = OutlApp.GetNamespace("MAPI")
 
        FirstFolder = oNS.Folders
        FirstFolder2 = oNS.Folders
        oFolder = FirstFolder.GetFirst()
        InFolder = oFolder.Folders
        FirstFolder.GetFirst()
        FirstFolder2.GetFirst()
 
    m = 0
 
        Dim tn As TreeNode
        Do Until FirstFolder Is Nothing
            Try
                tn = New TreeNode
                tn.Text = oFolder.Name
                tn.Tag = m
                T.Nodes.Add(tn)
 
                If Not oFolder.Folders.Count = 0 Then GetFolders(InFolder, tn)
Again:
                oFolder = FirstFolder2.GetNext()
                If oFolder Is Nothing Then Exit Do
                InFolder = FirstFolder.GetNext.Folders
            Catch ex As Exception
                GoTo Again
            End Try
        Loop
    End Sub
 
    Private Sub GetFolders(ByVal FirstFolder As Outlook.Folders, ByVal HN As TreeNode)
        m += 1
        Dim tn As TreeNode
        Dim oFolder As Outlook.MAPIFolder = FirstFolder.GetFirst
        Do Until oFolder Is Nothing
            tn = New TreeNode
            tn.Text = oFolder.Name
            tn.Tag = m
            HN.Nodes.Add(tn)
            If Not oFolder.Folders.Count = 0 Then HaalFolders(FirstFolder.GetFirst.Folders, tn)
            oFolder = FirstFolder.GetNext
        Loop
        m -= 1
    End Sub

Anyone knows a better solution?
You see I got a 2 folder construction, maybe one to much,
but I don't know how.
