（4096，“Microsoft Outlook”，“尝试的操作失败。找不到对象。”，无，0，2147221233），无）Outlook中的错误

Question

我目前正在使用pywin32.com python库将邮件移动到outlook中的特定文件夹。 我必须将文件夹路径设置为可配置的，因此我创建了一个python文件，将文件夹路径作为列表保存在其中。FoldersConfig.py文件的内容是：

#相对于收件箱文件夹的文件夹名称

mailBox = "mailbox-name"
nagiosDestinationFolder = ["Resolved_Clients","Internal","Nagios alerts"] #all these folders are been created in outlook with exact names.

然后还有另一个文件将邮件移动到目标文件夹。就我而言，Nagios alerts是我的目标文件夹。MoveNagiosAlerts.py文件的代码段为：

outlook = client.Dispatch("Outlook.Application").GetNamespace("MAPI")
    stores = outlook.Stores
    for store in stores:
        mailBox = FoldersConfig.mailBox
        if(mailBox in store.DisplayName):
            rootFolder = store.GetDefaultFolder(6) #rootFolder is the Inbox folder
            break 
    
    def moveWarnings():
        print("Moving warning mails...")
        warnCount = 0
        scriptingDictionary = {}
        nagiosDestFolder = rootFolder
        for i in FoldersConfig.nagiosDestinationFolder:
            nagiosDestFolder = nagiosDestFolder.Folders(i)
        print(nagiosDestFolder)
        for i in range(rootFolder.Items.Count-1,0,-1):
            msg = rootFolder.Items[i]
            if(msg.Body.find("State: WARNING") != -1):
               msg.Move(nagiosDestFolder)
               warnCount+=1
        return warnCount

运行MoveNagiosAlerts.py文件时弹出的错误是：

Root folder(Inbox):  Inbox

Outlook folder structure for your refrence

我的问题是为什么会抛出此错误？？它有时工作正常，但大多数情况下会抛出此错误。你知道我的代码到底出了什么问题吗？？还是outlook的问题？

根据我的理解，我认为pywin客户端无法获取列表中的文件夹。但不确定这是否是原因

Answer 1

我注意到代码中有以下循环：

for i in range(rootFolder.Items.Count-1,0,-1):
            msg = rootFolder.Items[i]

移动项目时，集合中的项目数将减少。所以，你需要为此做好准备

另外，如果只想移动与条件相对应的项，则需要使用Find/FindNext或Restrict方法来获取这些项，并在不检查任何其他属性的情况下移动所有项。请在以下文章中阅读有关这些方法的更多信息：
