Python-属性错误（在其他PC上运行脚本）

Question

在这里完成初学者。 下面的脚本在PC1上运行良好，但在PC2上却无法正常运行。 我收到以下信息：

Traceback (most recent call last):
  File "C:\Users\sgreene\Documents\indices.py", line 44, in <module>
    if msg.SentOn.strftime('20%y-%m-%d') == str(date.today() + datetime.timedelta(lagdays)):
  File "C:\Program Files\Python36-32\lib\site-packages\win32com\client\dynamic.py", line 527, in __getattr__
    raise AttributeError("%s.%s" % (self._username_, attr))
AttributeError: <unknown>.SentOn

据我所知，两个版本的pypiwin32（win32com）在两台PC上都是相同的（版本223），所以我不确定如何处理。

注意：我也正在寻找一个特定的邮件文件夹。 目前，我已将其设置为默认收件箱（6）。 如何使脚本搜索一个专门命名的邮件文件夹？

            from win32com.client import Dispatch

Answer 1

您假设收件箱中只有MailItem对象。 您还可以具有ReportItem或MeetingItem对象-它们不公开SentOn属性。 首先检查Class属性（所有OOM对象都将其公开）-对于MailItem对象，它为43（ OlObjectClass.olMail ）。

for msg in all_inbox:
  if msg.Class = 43 Then
   ...
  End If
