如何使用python打开pst文件（outlook邮件文件）？

Question

我有pst文件，我想用python打开它，我该怎么办

我试着去图书馆，但没用

我的代码是：

import mailparser

mail = mailparser.parse_from_bytes(byte_mail)
mail = mailparser.parse_from_file('c/document/1.pst')
print(mail.attachments)  #list of all attachments

但是得到这个错误：mailparser.exceptions.MailParserOSError: To use this function you must install 'msgconvert' tool

这个好像行得通， https://pypi.org/project/libratom/

from libratom.lib.pff import PffArchive
from email import generator
from pathlib import Path

archive = PffArchive("bill_rapp_000_1_1.pst")
eml_out = Path(Path.cwd() / "emls")

if not eml_out.exists():
  eml_out.mkdir()

print("Writing messages to .eml")
for folder in archive.folders():
    if folder.get_number_of_sub_messages() != 0:
        for message in folder.sub_messages:
            name = message.subject.replace(" ", "_")
            name = name.replace("/","-")
            filename = eml_out / f"{message.identifier}_{name}.eml"
            filename.write_text(archive.format_message(message))
print("Done!")
