How do you fix the Mail Archiving Agent so it keeps documents in the right folders?

There is a sample modified database on The View's web site. What it does is create a categories field with a list of the folders the document belongs in so it can carry the folder location information with the document when it is moved into the archive.

Pawel Bartuzi (pawel.bartuzi@kir.com.pl) suggested fixing Lotus' archiving agents instead.
Modifications made to mail archiving agent ("Periodic Archive", Notes 4.6.5):

In the Declarations section added:

  'PB start
  Dim strlstFolders_g List As String
  'PB end

In the ProcessDocuments procedure added an the very beginning::

  'PB start
  Dim doc_l As NotesDocument
  Dim strUNID_l As String
  Dim lngCount_l As Long

  Forall a In dbSource.Views
    If a.IsFolder Then
      If (Not a.Name Like "(*)") Or (a.Name = "($Inbox)") Then
        Set doc_l = a.GetFirstDocument
        Do While Not doc_l Is Nothing
          strUNID_l = doc_l.UniversalID
          If Iselement(strlstFolders_g(strUNID_l)) Then
            strlstFolders_g(strUNID_l) = strlstFolders_g(strUNID_l) & ";" & a.Name
            strlstFolders_g(strUNID_l) = a.Name
            lngCount_l = lngCount_l + 1
            If Not session.IsOnServer Then  Print "Reading documents... " & a.Name & " - " & lngCount_l
          End If
          Set doc_l = a.GetNextDocument(doc_l)
      End If
    End If
  End Forall
 'PB end

and, an the beginning of the for...loop:

 'PB start
 If Not session.IsOnServer Then Print "Checking documents... " & i & " of " & numDocs
 'PB end

In the ArchiveDocument procedure, add at the very end:

 'PB start
 Dim strFolders_l As String
 Dim strFolder_l As String
 Dim intPos_l As Integer

 If Iselement(strlstFolders_g(docSource.UniversalID)) Then
   strFolders_l = strlstFolders_g(docSource.UniversalID)
   intPos_l = 0
   Do While Not Len(strFolders_l) = 0
     intPos_l = Instr(1, strFolders_l, ";")
     If intPos_l = 0 Then
       strFolder_l = strFolders_l
       strFolders_l = ""
       strFolder_l = Left$(strFolders_l, intPos_l - 1)
       strFolders_l = Right(strFolders_l, Len(strFolders_l) - (intPos_l))
     End If
     Call docArchive.PutInFolder(strFolder_l)
 End If
 'PB end


- Further optimizations can be done to minimize the size of the strlstFolders_g list by creating something like a "folder dictionary": then only folder IDs would be put in the list, it could be beneficial on very large mailboxes with very long folder names.
- Modifications to the "Archive selected documents" agent are basically the same, with the exception that some global variable names differ (docSource->note, docArchive->newnote, session->s, dbSource->sourcedb), also you have to be more careful where you place modifications as there are fewer procedures in "Archive selected..." than in "Periodic Archive" and they are longer.
