I created an application in Azure and exchanged the access_token with code, but I get an error when using jakarta.mail: “535 5.7.3 Authentication unsuccessful [SGXP274CA0007.SGPP274.PROD. outlook.com 2024 -11-12t03:19:03.964z 08dd02bfa482f37e]”.
An error occurred while using the microsoft SDK: “Request failed. The remote server returned an error:(401)”. Is there anything else I need to configure in Azure?

Since you have posted the question on Azure App Service tag ( one of tag), just to confirm, have provisioned the resource on Azure App Service? - We will add/adjust more tags to receive insights from the targetted audience/SMEs.
Just to highlight:
You may use the OAuth authentication service provided by Microsoft Entra (Microsoft Entra) to enable your application connect with IMAP, POP, or SMTP protocols to access Exchange Online in Office 365. Refer these docs for more info:
