Download Email attachments - Timeout Error

Question

I am trying to download Email attachments in Python.

I am mainly drawing on this:

Downloading multiple attachments using imaplib

I want to run the code once per week to download all new attachments (I delete old emails).

It was working (although very slowly) for a while, but since 3-4 days I always get a TimeoutError: [Errno 60] Operation timed out

Any ideas on how to deal with this error?

I am running the code in a Jupiter notebook on Safari or Chrome (Mac).

This is my code:

import email
import imaplib
import os
server = 'outlook.office.com' 
user = 'florian.xcvh@jiko.ch'
password = 'XXXXYYY'
outputdir = '/Users/florian/Documents/weekly_data'
subject = 'Interesting stuff' #subject line of the emails you want to download attachments from

# Connect to an IMAP server
def connect(server, user, password):
    m = imaplib.IMAP4_SSL(server)
    m.login(user, password)
    m.select()
    return m

# Download all attachment files for a given email
def downloaAttachmentsInEmail(m, emailid, outputdir):
    resp, data = m.fetch(emailid, "(BODY.PEEK[])")
    email_body = data[0][1]
    mail = email.message_from_bytes(email_body)
    if mail.get_content_maintype() != 'multipart':
        return
    for part in mail.walk():
        if part.get_content_maintype() != 'multipart' and part.get('Content-Disposition') is not None:
            open(outputdir + '/' + part.get_filename(), 'wb').write(part.get_payload(decode=True))

#download attachments from all emails with a specified subject line
def downloadAttachments(subject):
    m = connect(server, user, password)
    m.select("Inbox")
    typ, msgs = m.search(None, '(SUBJECT "' + subject + '")')
    msgs = msgs[0].split()
    for emailid in msgs:
        downloaAttachmentsInEmail(m, emailid, outputdir)

downloadAttachments(subject)
