Quick script I made to automate exporting all my emails from my Outlook inbox as .msg files and renaming them all to be the timestamp of the message

outlook_export.py

import os
import time
import shutil
import extract_msg
import dateparser
import datetime
import pygetwindow as gw
import pyautogui as gui
import traceback
import ctypes

OUT_PATH = "out"
BUF_PATH = "buf"
OLDEST = datetime.datetime(2020, 8, 21).timestamp()
TEST = False

if TEST:
	import sys
	file_path = os.path.join(BUF_PATH, os.listdir(BUF_PATH)[0])
	msg = extract_msg.Message(file_path)
	print(msg.date)
	msg.close()
	sys.exit()

w_outlook = gw.getWindowsWithTitle(' - Outlook')[0]
screen_w, screen_h = gui.size()
n = 0
while True:
	w_outlook.activate() # focus Outlook window
	time.sleep(0.1)
	gui.hotkey("ctrl", "c") # ctrl+c
	time.sleep(0.2)
	gui.press("up") # up
	# focus explorer window
	gui.moveTo(screen_w*0.75, screen_h*0.75)
	# for some reason gui.click() sometimes fails with FileNotFoundError so workaround:
	ctypes.windll.user32.mouse_event(2, 0, 0, 0,0) # left down
	ctypes.windll.user32.mouse_event(4, 0, 0, 0,0) # left up
	time.sleep(0.1)
	gui.hotkey("ctrl", "v") # ctrl + v

	# poll buf folder
	files = []
	print("Waiting", end="", flush=True)
	while len(files) <= 0:
		files = os.listdir(BUF_PATH)
		print(",", end="", flush=True)
		time.sleep(0.2)

	break_flag = False

	for file in files: # should only be one but loop just in case
		file_path = os.path.join(BUF_PATH, file)

		# keep trying to read file (while still being written to)
		d = None
		while d is None:
			try:
				msg = extract_msg.Message(file_path)
				d = dateparser.parse(msg.date)
			except:
				pass
			print(".", end="", flush=True)
			time.sleep(0.2)
			msg.close()
			del msg # free up resource

		if d.timestamp() < OLDEST:
			timestamp = "{:010.0f}".format(d.timestamp()) + "{:03d}".format(n%1000)
			# n append to timestamp: crude system to avoid duplicate filenames if many emails received within same second (up to 1000 collisions handled)

			# move file (keep retrying until successful)
			while True:
				print("!", end="", flush=True)
				try:
					shutil.move(file_path, os.path.join(OUT_PATH, timestamp + ".msg"))
					break
				except PermissionError:
					traceback.print_exc()
					pass
				time.sleep(0.2)

			print("") # newline
			print("Done #{:04d}: {}".format(n, d.strftime("%c")))
			n += 1
			time.sleep(0.1)

		else:
			break_flag = True
			break

	if break_flag:
		break

print("Fin!")
