Exchangelib：修改电子邮件时出现 ErrorIrresolvableConflict

编程问答 2022-05-26

问题描述

我不得不使用 exchangelib 来修改我的一些电子邮件的主题。 以下是我用来修改电子邮件主题的代码行。 我正在将应用详细信息与 exchangelib 包一起使用。

credentials = OAuth2Credentials(client_id="",client_secret="",tenant_id="",identity=Identity(primary_smtp_address=""))

config = Configuration(credentials=credentials,auth_type=OAUTH2,service_endpoint='https://outlook.office365.com/EWS/exchange.asmx')

    account = Account(
        primary_smtp_address=mailBox_name,config=config,access_type=IMPERSONATION)
    inBox = account.inBox
    if inBox.all().exists():
        for message in inBox.all().order_by('-datetime_received')[:10]:
            message.subject = "Modified Subject"
            # message.save()
            message.save(update_fields=['subject'])

更新消息操作抛出以下错误：

message.save(update_fields=['subject'])


File "C:\Program Files\python38\lib\site-packages\exchangelib\items\item.py",line 97,in save
    item_id,changekey = self._update(
  File "C:\Program Files\python38\lib\site-packages\exchangelib\util.py",line 38,in wrapper
    return f(self,*args,**kwargs)
  File "C:\Program Files\python38\lib\site-packages\exchangelib\items\item.py",line 183,in _update
    res = UpdateItem(account=self.account).get(
  File "C:\Program Files\python38\lib\site-packages\exchangelib\services\common.py",line 93,in get
    res = list(self.call(**kwargs))
  File "C:\Program Files\python38\lib\site-packages\exchangelib\services\common.py",line 550,in _pool_requests
    for elem in self._get_elements(payload=payload_func(chunk,**kwargs)):
  File "C:\Program Files\python38\lib\site-packages\exchangelib\services\common.py",line 118,in _get_elements
    for i in self._response_generator(payload=payload):

    container_or_exc = self._get_element_container(message=msg,name=self.element_container_name)
  File "C:\Program Files\python38\lib\site-packages\exchangelib\services\common.py",line 373,in _get_element_container
    raise self._get_exception(code=response_code,text=msg_text,msg_xml=msg_xml)
exchangelib.errors.ErrorIrresolvableConflict: The send or update operation Could not be performed because the change key passed in the request does not match the current change key for the item.
