    VBA Code - I cannot compute

    Hey earth people,

    I have a problem understanding my own code. I left it at a stop only to investigate more before coding more. Its weird sometimes when you can create something but you're confused how you did it. I haven't programmed in VBA for a little over a year. All knowledge is asleep. I'm hoping someone might be able to compile the code in english to tell me what its doing, and how it's doing it. Mainly my focus is on, a variable declared as "oFolder" and the my For Each loop, where it prints "10XBilling", what I'm confused is how is it that I only declared oFolder, but it can see this calendar; it somehow is strangly entangled with set command, "Set item = Outlook.ActiveExplorer.CurrentFolder"

    Here's the code. Hopefully I explained myself. I'm not exactly all there. I need energy juice after writing this.

    Sub Whatever2()
    Dim Outlook As Object    'Outlook.Application
    Dim oNS As Object    'Outlook.Namespace
    Dim oFolder As Object    'Outlook.folder
    Dim item As Object
    Dim objOwner As Outlook.Recipient
    ' ---- set Outlook Instance
    On Error Resume Next
    Set Outlook = GetObject(, "Outlook.Application") 'Bind an existing instance of Outlook
    If Err.Number <> 0 Then 'Could not get instance, so create a new one
    Err.Clear
    Set Outlook = CreateObject("Outlook.Application")
    End If
    On Error GoTo Error_Handler
    Set oNS = Outlook.GetNamespace("MAPI")
    'use the default folder
    Set item = Outlook.ActiveExplorer.CurrentFolder
    'print test
    Debug.Print "Hello 1"
    'do whatever'
    On Error Resume Next
    For Each item In oFolder.items
    Debug.Print item.GetFirst
    Next item
    On Error GoTo Error_Handler
    Error_Handler_Exit:
    On Error Resume Next
    If Not oPrp Is Nothing Then Set oPrp = Nothing
    If Not oItem Is Nothing Then Set oItem = Nothing
    If Not oFolder Is Nothing Then Set oFolder = Nothing
    If Not oNameSpace Is Nothing Then Set oNameSpace = Nothing
    If Not oOutlook Is Nothing Then Set oOutlook = Nothing
    Exit Sub
    Error_Handler:
    MsgBox "The following error has occurred" & vbCrLf & vbCrLf & _
    "Error Number: " & Err.Number & vbCrLf & _
    "Error Source: Outlook_ExtractAppointments" & vbCrLf & _
    "Error Description: " & Err.Description & _
    Switch(Erl = 0, "", Erl <> 0, vbCrLf & "Line No: " & Erl) _
    , vbOKOnly + vbCritical, "An Error has Occurred!"
    Resume Error_Handler_Exit
    End Sub
