This is an example that shows how to use Camel on Spring Boot to connect with IMAP protocol and access email data for Office 365 users using OAuth2 authentication.
The application will use the client credentials grant flow to get the access token and use it to authenticate IMAP connections.
-
To use OAuth, an application must be registered with Azure Active Directory. Follow the instructions listed in Register an application with the Microsoft identity platform to register a new application.
-
Enable application to access Exchange mailboxes via client credentials flow adding IMAP.AccessAsApp permission. Instructions here
-
Create and register your Azure Active Directory application’s service principal in Exchange via Exchange Online PowerShell. Instructions here
-
Edit the application.properties adding the values to the properties marked with
<FILL-ME>
tag
You can run this example using:
mvn spring-boot:run
And you should see this output:
