How to Find an Outlook Admin’s Email with Python

What will you learn?

In this tutorial, you will discover how to programmatically find the email address of an Outlook administrator using Python. By leveraging Microsoft’s Graph API and OAuth2 protocol, you can access vital information within the Microsoft Cloud ecosystem.

Introduction to Problem and Solution

Automating administrative tasks or enhancing security measures often requires identifying Outlook administrators’ email addresses. This guide simplifies this process by utilizing Python to interact with Microsoft’s Graph API effectively.

Short Intro

This guide aims to simplify complex operations by providing easy-to-understand Python code for locating an Outlook admin’s email address programmatically.

Diving Into the Problem and Its Solution

To achieve our goal of finding an Outlook admin’s email address, we need to follow these key steps:

  1. Registering Application in Azure AD: Register your application in Azure Active Directory (AD) to obtain necessary permissions and credentials like client ID, tenant ID, and client secret.

  2. Authentication and Requesting Data: Utilize OAuth2 protocol along with the Microsoft Authentication Library (MSAL) for Python to authenticate your application and make GET requests against the Graph API endpoints holding user information.


from msal import ConfidentialClientApplication
import requests

CLIENT_ID = 'Your-App-Client-ID'
TENANT_ID = 'Your-Tenant-ID'
CLIENT_SECRET = 'Your-Client-Secret'

app = ConfidentialClientApplication(

token_response = app.acquire_token_for_client(scopes=[""])

if "access_token" in token_response:
    url = ""

    headers = {
        'Authorization': f'Bearer {token_response["access_token"]}'

    response = requests.get(url=url, headers=headers)

    if response.status_code == 200:
        print("Success! Fetched user data:")

   print("Could not acquire access token")

Below is a breakdown of the code snippet:

Step Description
1 Initialization: Create a ConfidentialClientApplication object with Azure AD credentials.
2 Token Acquisition: Acquire an access token for Graph API using MSAL library.
3 Making Requests: Make a GET request to fetch user data from /users endpoint with proper authentication headers.
  1. How do I register my application in Azure AD?

  2. To register your application in Azure AD: 1. Go to Azure Portal. 2. Navigate through Azure Active Directory > App registrations > New registration. 3. Follow prompts providing necessary details such as name and redirect URIs if applicable.

  3. What are scopes when acquiring tokens?

  4. Scopes define permissions requested by your application e.g., reading user profiles or sending mails on their behalf.

  5. Can I use this method for other Office 365 services?

  6. Yes! Modify scopes/request URLs while respecting required permissions for services like SharePoint or OneDrive.

  7. How do I handle errors/exceptions?

  8. Wrap network calls into try-except blocks handling exceptions gracefully e.g., requests.exceptions.RequestException.

  9. Is there rate limiting on Graph API?

  10. Microsoft imposes throttling limits ensuring equitable resource usage amongst consumers so monitor response headers like Retry-After.


By mastering the process of finding an Outlook admin’s email address using Python, you unlock possibilities for integrating various Office 365 services into your projects seamlessly. Embrace cloud computing capabilities at your fingertips!
