How to Configure Azure AD Service Principal to Send Emails from Mailbox via Logic App?

Question

I have created a Service Principal in Azure AD, and I want it to be able to send emails from its mailbox. This is for an upcoming Logic App that I am building, where I need the Service Principal to send emails to recipients with log ingestion reports.

Could anyone guide me on how to configure the Service Principal to send emails? Specifically, I'm looking for the correct permissions and steps needed to allow the Service Principal to interact with the mailbox and send messages via the Logic App.

Thanks in advance for your help!

Hello Bishal Das,

Thank you for reaching out to Microsoft Support!

Depending on your needs, it is recommended that you use the Graph API to send email.

When using the Graph API, you first need to grant the application permission. You can grant the application permission Mail.Send, and then get the token. See the documentation for details:

The obtained token can then be used to request the sendMail endpoint to send mail.

If you need to send emails programmatically, Graph SDKs is recommended.

Hope this helps.
