Save Outlook attachment to disk - vba

Question

I found numerous examples of VBA scripts to automatically move attachments to my hard drive. This one I've found online works when I run the macro in Outlook as is, but will not work when I set it to a rule.
When I run the macro without the "item as outlook.mailitem" parameter in the sub header and have the email containing the file I want saved selected, it will function properly.
However, as soon as I add that information so I can run it as a rule, outlook throws an error and it disables the rule.
Option Explicit
Public Sub moveAttachmentsAlpha(item As Outlook.MailItem)
Dim objOL As Outlook.Application
Dim objMsg As Outlook.MailItem 'Object
Dim objAttachments As Outlook.Attachments
Dim objSelection As Outlook.Selection
Dim i As Long
Dim lngCount As Long
Dim strFile As String
Dim strFolderpath As String
Dim strDeletedFiles As String
' Get the path to your My Documents folder
strFolderpath = "C:\DailyFlash\"
On Error Resume Next
' Instantiate an Outlook Application object.
Set objOL = CreateObject("Outlook.Application")
' Get the collection of selected objects.
Set objSelection = objOL.ActiveExplorer.Selection
' Check each selected item for attachments. If attachments exist,
' save them to the strFolderPath folder and strip them from the item.
For Each objMsg In objSelection
' This code only strips attachments from mail items.
' If objMsg.class=olMail Then
' Get the Attachments collection of the item.
Set objAttachments = objMsg.Attachments
lngCount = objAttachments.Count
strDeletedFiles = ""
If lngCount > 0 Then
' We need to use a count down loop for removing items
' from a collection. Otherwise, the loop counter gets
' confused and only every other item is removed.
For i = lngCount To 1 Step -1
' Save attachment before deleting from item.
' Get the file name.
strFile = objAttachments.item(i).FileName
' Combine with the path to the Temp folder.
strFile = strFolderpath & strFile
' Save the attachment as a file.
objAttachments.item(i).SaveAsFile strFile
'write the save as path to a string to add to the message
'check for html and use html tags in link
If objMsg.BodyFormat <> olFormatHTML Then
strDeletedFiles = strDeletedFiles & vbCrLf & "<file://" & strFile & ">"
Else
strDeletedFiles = strDeletedFiles & "<br>" & "<a href='file://" & _
strFile & "'>" & strFile & "</a>"
End If
'Use the MsgBox command to troubleshoot. Remove it from the final code.
'MsgBox strDeletedFiles
Next i
' Adds the filename string to the message body and save it
' Check for HTML body
If objMsg.BodyFormat <> olFormatHTML Then
objMsg.Body = vbCrLf & "The file(s) were saved to " & strDeletedFiles & vbCrLf & objMsg.Body
Else
objMsg.HTMLBody = "<p>" & "The file(s) were saved to " & strDeletedFiles & "</p>" & objMsg.HTMLBody
End If
objMsg.Save
End If
Next
ExitSub:
Set objAttachments = Nothing
Set objMsg = Nothing
Set objSelection = Nothing
Set objOL = Nothing
End Sub

Keep most of the script. Remove the reference to Outlook.Selection and the for loop associated to it. Then, in it's place, assign item to objMsg to allow the rest of the of the script to function as normal. After testing I have decided to steal it and use it myself as well.
Public Sub moveAttachmentsAlpha(item As Outlook.MailItem)
Dim objMsg As Outlook.MailItem 'Object
Dim objAttachments As Outlook.Attachments
Dim i As Long
Dim lngCount As Long
Dim strFile As String
Dim strFolderpath As String
Dim strDeletedFiles As String
' Get the path to your My Documents folder
strFolderpath = "C:\temp\"
On Error Resume Next
Set objMsg = item
' This code only strips attachments from mail items.
' If objMsg.class=olMail Then
' Get the Attachments collection of the item.
Set objAttachments = objMsg.Attachments
lngCount = objAttachments.Count
strDeletedFiles = ""
If lngCount > 0 Then
' We need to use a count down loop for removing items
' from a collection. Otherwise, the loop counter gets
' confused and only every other item is removed.
For i = lngCount To 1 Step -1
' Save attachment before deleting from item.
' Get the file name.
strFile = objAttachments.item(i).FileName
' Combine with the path to the Temp folder.
strFile = strFolderpath & strFile
' Save the attachment as a file.
objAttachments.item(i).SaveAsFile strFile
'write the save as path to a string to add to the message
'check for html and use html tags in link
If objMsg.BodyFormat <> olFormatHTML Then
strDeletedFiles = strDeletedFiles & vbCrLf & "<file://" & strFile & ">"
Else
strDeletedFiles = strDeletedFiles & "<br>" & "<a href='file://" & _
strFile & "'>" & strFile & "</a>"
End If
Next i
' Adds the filename string to the message body and save it
' Check for HTML body
If objMsg.BodyFormat <> olFormatHTML Then
objMsg.Body = vbCrLf & "The file(s) were saved to " & strDeletedFiles & vbCrLf & objMsg.Body
Else
objMsg.HTMLBody = "<p>" & "The file(s) were saved to " & strDeletedFiles & "</p>" & objMsg.HTMLBody
End If
objMsg.Save
End If
ExitSub:
Set objAttachments = Nothing
Set objMsg = Nothing
Set objSelection = Nothing
Set objOL = Nothing
End Sub
FYI: I changed nothing after the line ' This code only strips attachments from mail items. Except for a Next
