Macro enviar correo múltiples destinatarios Excel-Lotus

Necesito que el siguiente código que tengo envíe los correos a más de una persona, he intentado colocar en cadena o unirlos con "&" pero no logro que envíe a más de uno.

Sub Email1()
Dim oSess As Object
Dim oDB As Object
Dim oDoc As Object
Dim oItem As Object
Dim direct As Object
Dim Var As Variant
Dim flag As Boolean
Dim Group As String
Dim Copia As String
Dim Copia1 As String
Group = "[email protected]"
Copia = "[email protected]"
Copia1 = "[email protected]"
Copia2 = "[email protected]"
Set oSess = CreateObject("Notes.NotesSession")
Set oDB = oSess.GETDATABASE("", "")
Call oDB.OPENMAIL
flag = True
If Not (oDB.IsOpen) Then flag = oDB.Open("", "")
If Not flag Then
MsgBox "Can't open mail file: " & oDB.SERVER & " " & oDB.FILEPATH
GoTo exit_SendAttachment
End If
On Error GoTo err_handler
'Building Message
Set oDoc = oDB.CREATEDOCUMENT
Set oItem = oDoc.CREATERICHTEXTITEM("BODY")
oDoc.Form = "Memo"
oDoc.Subject = "Subject in here"
Call oDoc.ReplaceItemValue("SendTo", "[email protected], [email protected]")
oDoc.body = ""
oDoc.postdate = Date
oDoc.SaveMessageOnSend = True
'Attaching DATABASE
Call oItem.EmbedObject(1454, "", "ILocation of the file you wish to send here inc the .xls etc")
oDoc.visable = True
'Sending Message
oDoc.SEND False
exit_SendAttachment:
On Error Resume Next
Set oSess = Nothing
Set oDB = Nothing
Set oDoc = Nothing
Set oItem = Nothing
'Done
Exit Sub
err_handler:
If Err.Number = 7225 Then
MsgBox "File doesn't exist"
Else
MsgBox Err.Number & " " & Err.Description
End If
On Error GoTo exit_SendAttachment
End Sub
