Use an MS Graph service account and delegated access to send emails.

The keys to mastering sending emails with MS Graph

Developers wishing to incorporate email functionality into their apps now frequently use the Microsoft Graph for email sending. With MS Graph, developers may use a single API to access a wide range of Microsoft 365 services in addition to sending emails. This makes it easier to incorporate Microsoft services into apps, giving users a seamless and uniform experience.

There are several benefits to sending emails via MS Graph with a service account and delegated authorization, particularly in terms of security and access flexibility. Through this technique, programs can operate on behalf of users without the users' direct involvement, all the while tightly controlling the rights that are granted. The purpose of this tutorial is to go over the necessary procedures for setting up this environment and fixing typical problems.

Learn how to send emails using Microsoft Graph and assign permission.

The Microsoft Graph API's powerful feature of allowing email to be sent through it with a service account and delegated permission offers up new possibilities for enterprise applications. By using this technique, a user can delegate actions to an application instead of needing to intervene directly on every email sending operation. Because repeated communication procedures are automated, this leads to a considerable gain in both operational efficiency and user experience. In order to ensure that applications access resources safely and in compliance with organizational standards, using delegated permission with MS Graph necessitates a full understanding of the Microsoft 365 identity architecture and permissions.

The Microsoft Graph SDK for.NET is used in the technical implementation of MS Graph email sending, which makes interacting with the API easier. To get an access token, developers must first authenticate the application using Azure AD. Subsequently, an instance of GraphServiceClient, which offers the functionality required to produce and send emails, is created using this token. This procedure highlights the significance of appropriately handling permissions and access tokens to make sure the program doesn't use more resources than it has been given. Including these features in corporate apps facilitates communication, lowers the possibility of human error, and boosts productivity all around.

var authProvider = new InteractiveAuthenticationProvider(clientId, scopes);
var graphClient = new GraphServiceClient(authProvider);
var message = new Message
{
    Subject = "Sujet de test",
    Body = new ItemBody
    {
        ContentType = BodyType.Text,
        Content = "Corps du message de test"
    },
    ToRecipients = new List<Recipient>()
    {
        new Recipient
        {
            EmailAddress = new EmailAddress
            {
                Address = "destinataire@example.com"
            }
        }
    }
};
await graphClient.Me.SendMail(message, true).Request().PostAsync();

In-depth examination of email sending using MS Graph

One major advancement in the management of communications within enterprises is the integration of Microsoft Graph for email sending in enterprise apps. With the use of this technology, it is possible to access additional Microsoft 365 services, like calendars, contacts, and tasks, in addition to sending emails programmatically. The primary advantage is that it can automate labor-intensive, manual procedures that were previously manual, which raises productivity and lowers the possibility of mistakes.

A solid grasp of permission and security concepts inside the Microsoft environment is necessary to implement this functionality. The application's developers must make sure that it adheres to the least privilege guidelines by seeking just the permissions required to complete its duties. By doing this, security threats are reduced and private user data is safeguarded. Furthermore, as worries about data privacy increase, using Microsoft Graph APIs correctly is essential to upholding consumer confidence and adhering to legal requirements.
