我正在尝试使用 Python 3 和 exchangelib 删除我的 account.inbox 之外的文件夹中的所有电子邮件。

testFolder = account.root / 'Top of Information Store' / 'Test'    
emails = testFolder.all().order_by('-datetime_received')
for email in emails:
    email.delete()
    # FWIW
    #print(email.subject)
    #email.move(to_another_folder)
    #both work fine.

以上仅打印所有电子邮件及其属性

我也试过：

items=[]
testFolder = account.root / 'Top of Information Store' / 'Test'    
emails = testFolder.all().order_by('-datetime_received')
for email in emails:
    items.append(Message(folder=testFolder))
items.save()
items.delete()

上面挂起并给出内存错误：

File "C:\Python36-32\lib\site-packages\exchangelib\services.py", line 89, in _
get_elements
    response = self._get_response_xml(payload=payload)
  File "C:\Python36-32\lib\site-packages\exchangelib\services.py", line 171, in
_get_response_xml
    res = self._get_soap_payload(response=r, **parse_opts)
  File "C:\Python36-32\lib\site-packages\exchangelib\services.py", line 260, in
_get_soap_payload
    root = to_xml(response.iter_content())
  File "C:\Python36-32\lib\site-packages\exchangelib\util.py", line 365, in to_x
ml
    return parse(stream, parser=forgiving_parser)
  File "C:\Python36-32\lib\site-packages\defusedxml\lxml.py", line 134, in parse
  elementtree = _etree.parse(source, parser, base_url=base_url)
  File "src\lxml\etree.pyx", line 3424, in lxml.etree.parse
  File "src\lxml\parser.pxi", line 1857, in lxml.etree._parseDocument
  File "C:\Python36-32\lib\site-packages\exchangelib\util.py", line 340, in getv
alue
    res = b''.join(self._bytes_generator)
MemoryError

我不确定我还应该尝试什么，尤其是因为前者可以很好地移动和打印电子邮件。

无需先收集物品。正如您所发现的，这将消耗大量内存。相反，您可以.delete()直接在 QuerySet 上调用。这将仅获取项目 ID 并批量删除它们。

还有一种.empty()方法可以调用EmptyFolder服务。这将删除文件夹中的所有项目，甚至不获取 ID：

testFolder.all().delete()
# Or even faster:
testFolder.empty()

也许而不是删除尝试移动到垃圾箱？还是软删除？
