使用win32com和/或活动目录，如何按名称访问电子邮件文件夹？

Question

在python w/Outlook 2007中，使用win32com和/或active_目录，如何获取对子文件夹的引用，以便可以将邮件项目移动到此子文件夹？

我的收件箱结构如下：

    Inbox
      |
      +-- test
      |
      `-- todo

我可以访问收件箱文件夹，如：

import win32com.client
import active_directory
session = win32com.client.gencache.EnsureDispatch("MAPI.session")
win32com.client.gencache.EnsureDispatch("Outlook.Application")
outlook = win32com.client.Dispatch("Outlook.Application")
mapi = outlook.GetNamespace('MAPI')
inbox =  mapi.GetDefaultFolder(win32com.client.constants.olFolderInbox)
print '\n'.join(dir(inbox))

但是当我试图获取每个Microsoft's example的子目录test时，inbox对象没有Folders接口或任何获取子目录的方法。

如何获得指向Foldersubdir的test对象？

Answer 1

这对我来说很有用，可以将邮件项移动到“test”子目录中（通过去掉gencache的内容来简化）：

import win32com.client

olFolderInbox = 6
olMailItem = 0

outlook = win32com.client.Dispatch("Outlook.Application")
mapi = outlook.GetNamespace('MAPI')
inbox =  mapi.GetDefaultFolder(olFolderInbox)

item = outlook.CreateItem(olMailItem)
item.Subject = "test"

test_folder = inbox.Folders("test")
item.Move(test_folder)

Answer 2

对我有用的是遍历文件夹名。（当我发布这个问题时，我不知道文件夹的名称）。

import win32com.client
import active_directory
session = win32com.client.gencache.EnsureDispatch("MAPI.session")
win32com.client.gencache.EnsureDispatch("Outlook.Application")
outlook = win32com.client.Dispatch("Outlook.Application")
mapi = outlook.GetNamespace('MAPI')
inbox =  mapi.GetDefaultFolder(win32com.client.constants.olFolderInbox)

fldr_iterator = inbox.Folders   
desired_folder = None
while 1:
    f = fldr_iterator.GetNext()
    if not f: break
    if f.Name == 'test':
        print 'found "test" dir'
        desired_folder = f
        break

print desired_folder.Name

我意识到这是一个老问题，但我最近一直在使用win32com软件包，发现文档很麻烦，至少可以这么说……我希望有人，有一天能拯救我在试图理解MSDN的解释时所经历的混乱

下面是一个python脚本的示例，它可以遍历Outlook文件夹，在我需要的地方访问电子邮件。

免责声明 我在代码周围移动了一下，取出了一些敏感信息，所以如果你想复制粘贴并运行它，祝你好运。

import win32com
import win32com.client
import string
import os
# the findFolder function takes the folder you're looking for as folderName,
# and tries to find it with the MAPIFolder object searchIn

def findFolder(folderName,searchIn):
try:
    lowerAccount = searchIn.Folders
    for x in lowerAccount:
        if x.Name == folderName:
            print 'found it %s'%x.Name
            objective = x
            return objective
    return None
except Exception as error:
    print "Looks like we had an issue accessing the searchIn object"
    print (error)
    return None

def main():

outlook=win32com.client.Dispatch("Outlook.Application")

ons = outlook.GetNamespace("MAPI")

#this is the initial object you're accessing, IE if you want to access
#the account the Inbox belongs too
one = '<your account name here>@<your domain>.com'

#Retrieves a MAPIFolder object for your account 
#Object functions and properties defined by MSDN at 
#https://msdn.microsoft.com/en-us/library/microsoft.office.interop.outlook.mapifolder_members(v=office.14).aspx
Folder1 = findFolder(one,ons)

#Now pass you're MAPIFolder object to the same function along with the folder you're searching for
Folder2 = findFolder('Inbox',Folder1)

#Rinse and repeat until you have an object for the folder you're interested in
Folder3 = findFolder(<your inbox subfolder>,Folder2)

#This call returns a list of mailItem objects refering to all of the mailitems(messages) in the specified MAPIFolder
messages = Folder3.Items

#Iterate through the messages contained within our subfolder
for xx in messages:
    try:
        #Treat xx as a singular object, you can print the body, sender, cc's and pretty much every aspect of an e-mail
       #In my case I was writing the body to .txt files to parse...
        print xx.Subject,xx.Sender,xx.Body
       #Using move you can move e-mails around programatically, make sure to pass it a 
        #MAPIFolder object as the destination, use findFolder() to get the object
        xx.Move(Folder3)


    except Exception as err:
        print "Error accessing mailItem"
        print err       


if __name__ == "__main__":
main()

希望这不会弊大于利。
