Looping through inbox - object sets itself to nothing

hi all,

I've written a script that loops through all the emails in my inbox and, if a folder exists that match the simle criteria it moves it there. for some strange reason after going through a few time the Email object becomes nothing and i cant work out why. Oddly enough if i wait a few seconds i can continue with the code (simply pressing f5.)

Code:

---



Private Sub loop_test()




    Set objNS = GetNamespace("MAPI")
    Set objinbox = objNS.GetDefaultFolder(olFolderInbox)
    Set objFolder = objNS.GetDefaultFolder(olFolderInbox).Folders("Opportunities").Folders("Customers")
   
    Dim currenttime As Date
   
    For Each Email In objinbox.Items
    For Each SubFolder In objFolder.Folders
        If InStr(Email.subject, SubFolder.Name) Then
           
            Email.Move SubFolder
        End If


    Next SubFolder
    Next Email




End Sub

thanks for any help

Try the following. You should loop backwards through the messages as shown or the process can lose track of the count when the messages are moved.

Code:

---

Public Sub loop_test()
Dim i As Long
Dim objNS As NameSpace
Dim objInbox As Folder
Dim objFolder As Folder
Dim subFolder As Folder
Dim olMail As MailItem

    Set objNS = GetNamespace("MAPI")
    Set objInbox = objNS.GetDefaultFolder(olFolderInbox)
    Set objFolder = objNS.GetDefaultFolder(olFolderInbox).folders("Opportunities").folders("Customers")

    For i = objInbox.items.Count To 1 Step -1
        If TypeName(objInbox.items(i)) = "MailItem" Then
            Set olMail = objInbox.items(i)
            For Each subFolder In objFolder.folders
                If InStr(olMail.Subject, subFolder.Name) Then
                    olMail.Move subFolder
                    Exit For
                End If
                DoEvents
            Next subFolder
        End If
        DoEvents
    Next i
    Set objNS = Nothing
    Set objInbox = Nothing
    Set olMail = Nothing
    Set objFolder = Nothing
    Set subFolder = Nothing
End Sub

Thanks Graham, that makes perfect sense and pretty obvious when you think about it.

thanks
