How to make this regex work in Excel?

[Shafty]

                            Dim MyRegExp As RegExp
                            Set MyRegExp = New RegExp
                            With MyRegExp
                                .Pattern = "(?<=Your message wasn't delivered to )(.*)(?= because)"
                                Cells.SpecialCells(xlCellTypeLastCell).Offset(1, -1).Value = MyRegExp.Execute(Returned_Mail.Body)
                            End With

With Hope,

So, Can we conclude that using RegularExpressions we can't do a "between String" Match in Excel VBA?
