Type mismatch when moving mail item from sent items

[welch.chris]

Hi

I am receiving a "type mismatch" error when trying to move an item
from Sent Items (what I am trying to do is move an item from the
default Sent Items, to the Sent Items in a separate mailbox, which is
configured to open with this one if that makes sense?) I am using
Exchange Server in Outlook 2003.

I've basically done very little VBA for Outlook, so most of this is
taken from examples that I've found online and modified to suit.

I think (having used the VarType function) the GetFolder sub is
returning a string as opposed to a MAPIFolder, but I can't work out
why.. however, if I use the 'Display' function on the folder variable,
the correct folder is displayed, so that could be a red herring.

Many thanks in advance for any help anyone may be able to give!

My code thus far is:

Option Explicit

Dim dest_folder As String
Dim safe_mail_item
Dim ol_app As Outlook.Application
Dim namespace
Dim sent_as_safe
Dim safe_current_user
Dim folder As Outlook.MAPIFolder
Dim folder_root
Dim folder_count
Dim sent_folder

Private WithEvents sent_items As Items

Private Sub Application_Startup()
Set ol_app = CreateObject("Outlook.Application")
Set namespace = ol_app.GetNamespace("MAPI")
Set sent_folder = namespace.GetDefaultFolder(olFolderSentMail)
Set sent_items = sent_folder.Items
Set namespace = Nothing
Set ol_app = Nothing
End Sub

Private Sub sent_items_ItemAdd(ByVal Item As Object)
Dim msg
If Item.Class = olMail Then
dest_folder = "Mailbox - Waterline Limited - Direct Deliveries
\Sent Items"
'Set ol_app = CreateObject("Outlook.Application")
'Set namespace = ol_app.GetNamespace("MAPI")

Set folder = GetFolder(dest_folder)
MsgBox (VarType(folder))

If folder Is Nothing Then
msg = MsgBox("The folder: " + dest_folder + " cannot be
found", 0, "Destination folder not found")
Else
Item.Save
Item.Move (folder)
End If
End If
End Sub

' The following function was blatantly plagiarised! I've not changed
it, however, it appears to return a String though, as opposed to a
MAPIFolder?
Public Function GetFolder(strFolderPath As String) As
Outlook.MAPIFolder
' folder path needs to be something like
' "Public Folders\All Public Folders\Company\Sales"
Dim objApp As Outlook.Application
Dim objNS As Outlook.namespace
Dim colFolders As Outlook.Folders
Dim objFolder As Outlook.MAPIFolder
Dim arrFolders() As String
Dim I As Long
On Error Resume Next

strFolderPath = Replace(strFolderPath, "/", "\")
arrFolders() = Split(strFolderPath, "\")
Set objApp = CreateObject("Outlook.Application")
Set objNS = objApp.GetNamespace("MAPI")
Set objFolder = objNS.Folders.Item(arrFolders(0))
If Not objFolder Is Nothing Then
For I = 1 To UBound(arrFolders)
Set colFolders = objFolder.Folders
Set objFolder = Nothing
Set objFolder = colFolders.Item(arrFolders(I))
If objFolder Is Nothing Then
Exit For
End If
Next
End If

Set GetFolder = objFolder
Set colFolders = Nothing
Set objNS = Nothing
Set objApp = Nothing
End Function

That method returns a MAPIFolder object, look at the Function declaration.

If this code is running in an Outlook VBA macro do not use CreateObect() to
create a reference to the Outlook.Application object. Use the intrinsic
Application object instead:

Set ol_app = Application

If the Display method displays the correct target folder then I see no
reason why the code should not move the item from the source folder to the
target folder, assuming you have permission to create items in that mailbox.
Can you create a new Post item in that folder in the UI?

See if it helps if you use Move as the function it is:

Dim oMoved As Outlook.MailItem

Set oMoved = Item.Move(folder)
