While this question is fairly old, I believe the techniques in Robert McMurry's macro would work for this, because it sounds like exactly what the original question is looking for.
In the interest of trying to prevent the worst losses of bit-rot, here's the relevant block of code. The actual article has much more detail on what it's doing and possible enhancements such as adding recursion; this appears to work on just a single folder ("Inbox") and can probably be used as a starting point.
' Declare all variables.
Dim objOutlook As Outlook.Application
Dim objNamespace As Outlook.NameSpace
Dim objSourceFolder As Outlook.MAPIFolder
Dim objDestFolder As Outlook.MAPIFolder
Dim objVariant As Variant
Dim lngMovedMailItems As Long
Dim intCount As Integer
Dim intDateDiff As Integer
Dim strDestFolder As String
' Create an object for the Outlook application.
Set objOutlook = Application
' Retrieve an object for the MAPI namespace.
Set objNamespace = objOutlook.GetNamespace("MAPI")
' Retrieve a folder object for the source folder.
Set objSourceFolder = objNamespace.GetDefaultFolder(olFolderInbox)
' Loop through the items in the folder. NOTE: This has to
' be done backwards; if you process forwards you have to
' re-run the macro an inverese exponential number of times.
For intCount = objSourceFolder.Items.Count To 1 Step -1
' Retrieve an object from the folder.
Set objVariant = objSourceFolder.Items.Item(intCount)
' Allow the system to process. (Helps you to cancel the
' macro, or continue to use Outlook in the background.)
' Filter objects for emails or meeting requests.
If objVariant.Class = olMail Or objVariant.Class = olMeetingRequest Then
' This is optional, but it helps me to see in the
' debug window where the macro is currently at.
' Calculate the difference in years between
' this year and the year of the mail object.
intDateDiff = DateDiff("yyyy", objVariant.SentOn, Now)
' Only process the object if it isn't this year.
If intDateDiff > 0 Then
' Calculate the name of the personal folder.
strDestFolder = "Personal Folders (" & _
Year(objVariant.SentOn) & ")"
' Retrieve a folder object for the destination folder.
Set objDestFolder = objNamespace.Folders(strDestFolder).Folders("Inbox")
' Move the object to the destination folder.
' Just for curiousity, I like to see the number
' of items that were moved when the macro completes.
lngMovedMailItems = lngMovedMailItems + 1
' Destroy the destination folder object.
Set objDestFolder = Nothing
' Display the number of items that were moved.
MsgBox "Moved " & lngMovedMailItems & " messages(s)."
