Chapter 39. Mail Microsoft Oauth

Since Camel 3.18.4.

The Mail Microsoft OAuth2 provides an implementation of org.apache.camel.component.mail.MailAuthenticator to authenticate IMAP/POP/SMTP connections and access to Email via Spring’s Mail support and the underlying JavaMail system.

Add the following dependency to your pom.xml for this component: 

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-mail-microsoft-oauth</artifactId>
    <version>3.20.1.redhat-00031</version>
    <!-- use the same version as your Camel core version -->
</dependency>

Importing camel-mail-microsoft-oauth will automatically import camel-mail component.

To use OAuth, an application must be registered with Azure Active Directory. Follow the instructions to register a new application.

Procedure

  1. Enable the application to access Exchange mailboxes via client credentials flow. For more information, see Authenticate an IMAP, POP or SMTP connection using OAuth
  2. Once everything is set up, declare and register in the registry, an instance of org.apache.camel.component.mail.MicrosoftExchangeOnlineOAuth2MailAuthenticator.
  3. For Example, in a Spring Boot application: 
@BindToRegistry("auth")
public MicrosoftExchangeOnlineOAuth2MailAuthenticator exchangeAuthenticator(){
    return new MicrosoftExchangeOnlineOAuth2MailAuthenticator(tenantId, clientId, clientSecret, "jon@doe.com");
}

 from("imaps://outlook.office365.com:993"
                    +  "?authenticator=#auth"
                    +  "&mail.imaps.auth.mechanisms=XOAUTH2"
                    +  "&debugMode=true"
                    +  "&delete=false")
