尝试使用Python从Outlook 2007发送邮件（win32com.client）

Question

我正在尝试使用Python启动一些Outlook 2007自动化。 我在以下线程上从Steve Townsend得到了一个很棒的脚本（下）： 通过Python发送Outlook电子邮件吗？

但我在开始时遇到了麻烦。

import win32com.client

def send_mail_via_com(text, subject, recipient, profilename="Outlook2007"):
    s = win32com.client.Dispatch("Mapi.Session")
    o = win32com.client.Dispatch("Outlook.Application")
    s.Logon(profilename)

    Msg = o.CreateItem(0)
    Msg.To = recipient

    Msg.CC = "moreaddresses here"
    Msg.BCC = "address"

    Msg.Subject = subject
    Msg.Body = text

    #attachment1 = "Path to attachment no. 1"
    #attachment2 = "Path to attachment no. 2"
    #Msg.Attachments.Add(attachment1)
    #Msg.Attachments.Add(attachment2)

    Msg.Send()


send_mail_via_com("test text","test subject", "removed@security.obv","Outlook2007")

但是我收到以下错误：

Traceback (most recent call last):
  File "C:\Python32\lib\site-packages\win32com\client\dynamic.py", line 83, in _
GetGoodDispatch
    IDispatch = pythoncom.connect(IDispatch)
pywintypes.com_error: (-2147221005, 'Invalid class string', None, None)

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:\PROJECTS\Python\send_mail_test.py", line 25, in <module>
    send_mail_via_com("test text","test subject", "removed@security.obv","Outloo
k2007")
  File "C:\PROJECTS\Python\send_mail_test.py", line 4, in send_mail_via_com
    s = win32com.client.Dispatch("Mapi.Session")
  File "C:\Python32\lib\site-packages\win32com\client\__init__.py", line 95, in
Dispatch
    dispatch, userName = dynamic._GetGoodDispatchAndUserName(dispatch,userName,c
lsctx)
  File "C:\Python32\lib\site-packages\win32com\client\dynamic.py", line 108, in
_GetGoodDispatchAndUserName
    return (_GetGoodDispatch(IDispatch, clsctx), userName)
  File "C:\Python32\lib\site-packages\win32com\client\dynamic.py", line 85, in _
GetGoodDispatch
    IDispatch = pythoncom.CoCreateInstance(IDispatch, None, clsctx, pythoncom.II
D_IDispatch)
pywintypes.com_error: (-2147221005, 'Invalid class string', None, None)

我可能错过了一些愚蠢的事情。

它是Python 3.2，并且已安装PyWin32

非常感谢

没关系...

import win32com.client
olMailItem = 0x0
obj = win32com.client.Dispatch("Outlook.Application")
newMail = obj.CreateItem(olMailItem)
newMail.Subject = "I AM SUBJECT!!"
newMail.Body = "I AM IN THE BODY\nSO AM I!!!"
newMail.To = "who_to_send_to@example.com"
#newMail.CC = "moreaddresses here"
#newMail.BCC = "address"
#attachment1 = "Path to attachment no. 1"
#attachment2 = "Path to attachment no. 2"
#newMail.Attachments.Add(attachment1)
#newMail.Attachments.Add(attachment2)
#newMail.display()
newMail.Send()

这适用于安装了PyWin32的Python 3.2.3。 我已经注释了一些行，如果你想玩这个。

import win32com.client

#some constants (from http://msdn.microsoft.com/en-us/library/office/aa219371%28v=office.11%29.aspx)
olFormatHTML = 2
olFormatPlain = 1
olFormatRichText = 3
olFormatUnspecified = 0
olMailItem = 0x0


obj = win32com.client.Dispatch("Outlook.Application")
newMail = obj.CreateItem(olMailItem)
newMail.Subject = "I AM SUBJECT!!"
newMail.BodyFormat = olFormatHTML    #or olFormatRichText or olFormatPlain
newMail.HTMLBody = "<h1>I am a title</h1><p>I am a paragraph</p>"
newMail.To = "who_to_send_to@example.com; anotherrecipient@email.fake"

# carbon copies and attachments (optional)

#newMail.CC = "moreaddresses here"
#newMail.BCC = "address"
#attachment1 = "Path to attachment no. 1"
#attachment2 = "Path to attachment no. 2"
#newMail.Attachments.Add(attachment1)
#newMail.Attachments.Add(attachment2)

# open up in a new window and allow review before send
newMail.display()

# or just use this instead of .display() if you want to send immediately
#newMail.Send()

上面的代码也适用于Python 2.7。 原始帖子中的错误是由以下原因引起的：

s = win32com.client.Dispatch（“ Mapi.Session”）追溯（最近一次调用）：文件“”，第1行，位于文件“ c：\\ Python27 \\ lib \\ site-packages \\ win32com \\ client__init __。py”中，第95行，在Dispatch调度中，userName = dynamic._GetGoodDispatchAndUserName（dispatch，userName，clsctx）文件“ c：\\ Python27 \\ lib \\ site-packages \\ win32com \\ client \\ dynamic.py”，第108行，在_GetGoodDispatchAndUserName中返回（_GetGoodDispatch（ IDispatch，clsctx），用户名）文件“ c：\\ Python27 \\ lib \\ site-packages \\ win32com \\ client \\ dynamic.py”，第85行，在_GetGoodDispatch中IDispatch = pythoncom.CoCreateInstance（IDispatch，None，clsctx，pythoncom.IID_IDispatch）

它曾经在Outlook 2003中工作。我想2007根本不需要MAPI和登录。
