How to get all mail from outlook via postman api

To retrieve all emails from Outlook using the Postman API, you'll need to follow these steps:

Prerequisites:

1. You have an Outlook account with a valid email address and password.
2. You have Postman installed on your computer.
3. You have the Outlook REST API enabled for your account. To do this, go to the Outlook settings, click on "View all Outlook settings", and then click on "Mail" > "Sync email". Make sure the "Use the Outlook REST API" option is enabled.

Step 1: Create an Azure AD application

To use the Outlook REST API, you need to create an Azure AD application. Follow these steps:

1. Go to the Azure portal (https://portal.azure.com/).
2. Click on "Azure Active Directory" in the navigation menu.
3. Click on "App registrations" and then click on "New registration".
4. Enter a name for your application, select "Web" as the platform, and enter a redirect URI (e.g., http://localhost).
5. Click on "Register" to create the application.
6. Note down the "Application (client) ID" and "Directory (tenant) ID" values.

Step 2: Create an access token

To authenticate with the Outlook REST API, you need to obtain an access token. You can do this using the Azure AD application you created:

1. Go to the Azure portal and navigate to your Azure AD application.
2. Click on "Certificates & secrets" and then click on "New client secret".
3. Enter a description for the secret and click on "Add".
4. Note down the "Client secret" value.
5. Use the following command to obtain an access token:

   curl -X POST \
   https://login.microsoftonline.com/{tenant_id}/oauth2/v2.0/token \
   -H 'Content-Type: application/x-www-form-urlencoded' \
   -d 'grant_type=client_credentials&client_id={client_id}&client_secret={client_secret}&resource=https://outlook.office.com/'

   Replace {tenant_id} with your Azure AD tenant ID, {client_id} with your Azure AD application ID, and {client_secret} with the client secret you created.

Step 3: Use the access token to retrieve emails

Now that you have an access token, you can use it to retrieve emails from Outlook using the Outlook REST API:

1. Open Postman and create a new request.
2. Set the request method to "GET".
3. Set the request URL to https://outlook.office.com/api/v2.0/me/mailfolders.
4. Set the "Authorization" header to Bearer {access_token} (replace {access_token} with the access token you obtained in Step 2).
5. Click on the "Send" button to send the request.
6. In the response, you should see a list of mailfolders. You can then use the mailfolderId to retrieve the emails:

   GET https://outlook.office.com/api/v2.0/me/mailfolders/{mailfolderId}/messages

   Replace {mailfolderId} with the ID of the mailfolder you want to retrieve emails from.

Tips and Variations:

• To retrieve emails from a specific folder, you can use the mailfolderId parameter in the request URL.
• To retrieve emails from a specific date range, you can use the startDateTime and endDateTime query parameters.
• To retrieve emails with a specific subject or sender, you can use the subject and from query parameters.
• You can also use the expand query parameter to retrieve additional information about the emails, such as attachments or recipients.
