Below is my Python code using win32com to read emails from a particular folder.

from logging import root
import os
import win32com.client
from datetime import datetime, timedelta
import zipfile

date_format = "%m/%d/%Y %H:%M"

def recursively_find_folder(folder, target_name):
    if folder.Name == target_name:
        return folder
    for subfolder in folder.Folders:
        found_folder = recursively_find_folder(subfolder, target_name)
        if found_folder:
            return found_folder

#function to check the emails mentioned in outlook folder and down load the attachements based on email subject
def download_attachments(folder_name, output_folder, start_time, end_time, target_subject):
    outlook_app = win32com.client.Dispatch("Outlook.Application").GetNamespace("MAPI")
    #root_folder = outlook_app.Folders.Item(3)  # Assume the first folder is the mailbox
    root_folder = outlook_app.GetDefaultFolder(6)  # Assume the first folder is the mailbox
      
    target_folder = recursively_find_folder(root_folder, folder_name)

    if target_folder:
        print(f"Found folder: {target_folder.Name}")

        # Iterate through items in the folder
        items = target_folder.Items
        items.sort("[ReceivedTime]", True)

        for item in items:
            print("Item:: ", item)
            print("    Subject:: ", item.Subject.lower())
            print("    Recevied Time: ", item.ReceivedTime)
            # Check if the email matches the criteria
            for subject in target_subject:
                print(subject)
                print("Email Received Time: ", datetime.strptime(item.ReceivedTime.strftime('%m/%d/%Y %H:%M'), date_format))
                if (
                    start_time <= datetime.strptime(item.ReceivedTime.strftime('%m/%d/%Y %H:%M'), date_format) <= end_time
                    and subject.lower().strip() in item.Subject.lower().strip()
                    and item.Attachments.Count > 0

                    print(f"Processing email: {item.Subject}")
                    for attachment in item.Attachments:

                        attachment.SaveAsFile(os.path.join(output_folder, attachment.FileName))
                        print(f"Downloaded attachment: {attachment.FileName}")
                else:
                    print("Nothing Happened!!!")

    else:
        print(f"Folder '{folder_name}' not found.")

    download_attachments(folder_to_download, output_directory, start_time, end_time, target_subject)
    
    find_and_unzip_report_file(output_directory, output_directory)

But the above code only reads email till 05/31/2024 and nothing after that. I tried running the code for other folders as well, but is the same. Emails scanned/processed only till 05/31.

Could someone please advise what exactly the issue in my code. Couldnt find any similar posts regarding this.
