Step 1. Get a Microsoft Entra client ID and tenant ID
In the Microsoft Azure portal, search for Microsoft Entra ID (formerly Azure Active Directory).
On the Entra ID overview page, select Add > App registration.
Name the app and select Register.
On the app details page, copy the Application (client) ID and Tenant ID.
Step 2. Get a Microsoft Azure private key
On the app homepage, go to Certificates & secrets > Client secrets.
Select New client secret.
Enter a description, choose an expiration date, and select Add.
Copy the generated client secret.
Step 3. Customize API Permissions
Go to the app’s API permissions tab.
Remove any default configured permissions.
Select Add a permission > Microsoft Graph > Application permissions.
Add the following permissions:
| API | Permission Name | Type | Description |
|---|---|---|---|
| Mail.ReadWrite | Application | Read and write access to mail | |
| Mail.Send | Application | Send mail as any user |
On the API permissions page, under Configured permissions, grant admin consent for the default directory.
Step 4. Connect your Microsoft Outlook account to ATS

- In Deel’s left sidebar, select Recruitment to expand its submenu.
- Select ATS.
If an announcement dialog appears over the ATS page, close it using the X in its upper-right corner.

- In the ATS workspace, select the Settings tab in the horizontal ATS navigation.

- In the Settings catalog, use the Search field to search for Email Management.

- Select the Email management result.
- It is listed with the description, “Manage your organization’s ATS email settings.”

- Confirm that the page heading is Email management and the breadcrumb shows Home / ATS / Settings / Email management.
- Depending on your organization’s configuration, add an email domain if prompted before provider connections are available.
Under Microsoft Outlook, select Connect.
Enter the Tenant ID, Client ID, and Client Secret you generated in the previous steps.
Select Submit.
Once complete, ATS will be able to send and manage candidate emails through your organization’s Microsoft Outlook account.
