Move specific mails from one folder to another - vba

Question

in Outlook I would like to have a FollowUp-Solution that checks a specific folder (Source Folder) if there are mails older than 1 days and moves them in another specific folder (Target Folder).
My problem is that it seems as my code isn't looping the SourceFolder properly. Some mails are moved but some old mails are still in the SourceFolder.
When I restart the Code some of the remaining mails are moved now but still some remain in the SourceFolder.
I tried to loop the Items in other ways (with; for each; do) but I guess my vba understanding is too bad to get a working solution.
Sub MoveFollowUpItems()
Dim FolderTarget As Folder
Dim FolderSource As Folder
Dim Item As Object
Dim FolderItems As Outlook.Items
Set FolderTarget = Application.GetNamespace("MAPI").GetDefaultFolder(olFolderInbox)
Set FolderSource = Application.GetNamespace("MAPI").GetDefaultFolder(olFolderInbox).Folders("FollowUp")
Set FolderItems = FolderSource.Items
For Each Item In FolderItems
If Item.ReceivedTime < Date - 1 Then '
Item.Move FolderTarget
End If
Next
End Sub
Does anyone know how to handle the propper looping?

Answer 1

For Each Loop is a great but When moving/deleting items Loop Through in Reverse Order you know count down (ie 3,2,1). In order to do this, you can incorporate Step -1 into your loop statement.
Also to improve your loop try using Items.Restrict Method (Outlook) on your date filter
Example
Option Explicit
Sub MoveFollowUpItems()
Dim FolderTarget As Folder
Dim FolderSource As Folder
Dim FolderItems As Outlook.Items
Set FolderTarget = Application.GetNamespace("MAPI").GetDefaultFolder(olFolderInbox)
Set FolderSource = Application.GetNamespace("MAPI").GetDefaultFolder(olFolderInbox).Folders("FollowUp")
Dim Filter As String
Filter = "#SQL=" & Chr(34) & "urn:schemas:httpmail:datereceived" & _
Chr(34) & " <= 'Date - 1' "
Set FolderItems = FolderSource.Items.Restrict(Filter)
Debug.Print FolderItems.Count
Dim i As Long
For i = FolderItems.Count To 1 Step -1
Debug.Print FolderItems(i) 'Immediate Window
' FolderItems(i).Move FolderTarget
Next
End Sub
