| == Camel Spring Boot Microsoft Exchange IMAP Oauth2 Authentication |
| |
| 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. |
| |
| |
| === Prerequisite |
| |
| * To use OAuth, an application must be registered with Azure Active Directory. |
| Follow the instructions listed in https://learn.microsoft.com/en-us/azure/active-directory/develop/quickstart-register-app[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 https://learn.microsoft.com/en-us/exchange/client-developer/legacy-protocols/how-to-authenticate-an-imap-pop-smtp-application-by-using-oauth#add-the-pop-and-imap-permissions-to-your-aad-application[here] |
| |
| * Create and register your Azure Active Directory application's service principal |
| in Exchange via Exchange Online PowerShell. Instructions https://learn.microsoft.com/en-us/exchange/client-developer/legacy-protocols/how-to-authenticate-an-imap-pop-smtp-application-by-using-oauth#register-service-principals-in-exchange[here] |
| |
| * Edit the link:src/main/resources/application.properties[application.properties] adding the values to the properties marked with ``<FILL-ME>`` tag |
