У меня проблема с OneDrive при попытке использовать VBA для доступа к файлам в папке OneDrive

Question

У меня есть книга OneDrive Excel, которую я открыл на локальном компьютере P C. У меня есть макрос, который создает счет-фактуру и сохраняет его в формате PDF в подкаталог на моем OneDrive. Пока проблем нет. Однако, когда я использую другой макрос для вложения ранее сохраненного файла, макрос не может найти файл. Я установил, что подкаталог существует с использованием

Function URLExists(url As String) As Boolean
    Dim Request As Object
    Dim ff As Integer
    Dim rc As Variant

    On Error GoTo EndNow
    Set Request = CreateObject("WinHttp.WinHttpRequest.5.1")

    With Request
      .Open "GET", url, False
      .Send
      rc = .StatusText
    End With
    Set Request = Nothing
    If rc = "OK" Then URLExists = True

    Exit Function
EndNow:
End Function

, но использование

Function FileExists(filename)
    On Error Resume Next
    FileExists = (Dir(filename) <> "")
End Function

дает мне файл не найден ошибка

Это полный подпункт 'SendEmail' что я использую.
