如何通过win32com实现Outlook自动化邮件的密级类型指定？

Absolutely! You can set your company's required email type (Public, General, Secret, etc.) using win32com with Outlook—here’s how to do it, depending on whether your company uses Outlook’s built-in sensitivity settings or a custom field.

1. Using Outlook's Built-in Sensitivity Property #

Outlook has a native Sensitivity property that maps directly to standard sensitivity levels like Confidential/Secret, Normal/General, etc. You can set this property directly via win32com without extra work.

First, here are the constant values (you can use either the numeric value or the named constant from win32.constants for readability):

• olNormal (0): General/Public (default setting)
• olPersonal (1): Personal
• olPrivate (2): Private
• olConfidential (3): Secret/Confidential

Add this line right after setting the email body in your script:

# Set to Secret/Confidential - swap the constant to match your company's required type
mail.Sensitivity = win32.constants.olConfidential

2. Handling Custom Company-Specific Email Type Fields #

If your company uses a custom user-defined field (like a dropdown labeled "Email Type" with options Public/General/Secret), you’ll need to interact with Outlook’s UserProperties collection to set this value.

Here’s how to add or update that custom field:

# Replace with the exact name of your company's custom field
custom_field_name = "Email Type"
# Set to your desired type: Public/General/Secret
desired_type = "Secret"

# Check if the custom field already exists on the email
field_found = False
for prop in mail.UserProperties:
    if prop.Name == custom_field_name:
        prop.Value = desired_type
        field_found = True
        break

# If the field doesn't exist, create it (adjust olText if your field uses a different type like olDropdown)
if not field_found:
    custom_prop = mail.UserProperties.Add(custom_field_name, win32.constants.olText)
    custom_prop.Value = desired_type

Fixed & Updated Full Script #

I also fixed a couple small typos in your original code (like tkinter as to → tkinter as tk and misspelled "attachment"):

import win32com.client as win32
import easygui
import tkinter as tk
from tkinter import filedialog

### easygui commands asking user for the inputs
fieldNames_text= ['','']
fieldNames= ['Subject','Link']
INPUT = easygui.multenterbox('Please fill in', 'FIN and PASSWORD', fieldNames, fieldNames_text)
answer = easygui.ynbox('Any attachment?', 'Attachment', ('Yes', 'No'))

### outlook handling
outlook = win32.Dispatch('outlook.application')
mail = outlook.CreateItem(0)
mail.To = 'name.surname@company.com'
mail.Subject = INPUT[0]
mail.Body = INPUT[1]

# --- Set email type/sensitivity ---
# Option 1: Use built-in sensitivity (uncomment below)
mail.Sensitivity = win32.constants.olConfidential  # Secret/Confidential

# Option 2: Use custom company field (uncomment below and adjust values)
# custom_field_name = "Email Type"
# desired_type = "Secret"
# field_found = False
# for prop in mail.UserProperties:
#     if prop.Name == custom_field_name:
#         prop.Value = desired_type
#         field_found = True
#         break
# if not field_found:
#     custom_prop = mail.UserProperties.Add(custom_field_name, win32.constants.olText)
#     custom_prop.Value = desired_type
# --- End email type setting ---

### attachment addition
if answer == True:
    root = tk.Tk()
    root.withdraw()
    file_path = filedialog.askopenfilename()
    mail.Attachments.Add(file_path)
else:
    pass

### mail sending
mail.Send()

Just uncomment the option that matches your company’s setup, adjust the values to fit your needs, and you’re ready to go!
