Spring Integration Email using IMAP Office 365 - email

Question

We are planning to use Spring Integration Mail Support with Office365 using IMAP however, it is not working as intended and we are getting authentication failed errors:
2022-12-19 08:45:12.257 ERROR --- [ scheduling-1] o.s.i.h.LoggingHandler : org.springframework.messaging.MessagingException: failure occurred while polling for mail; nested exception is javax.mail.AuthenticationFailedException: AUTHENTICATE failed.

Note: It is working fine using GMAIL via App password but for Office365 its not. Here is the sample bean we have:
#Bean
public IntegrationFlow iMapIntegrationFlow(
// Remove for brevity
) {
log.info("[Email Integration] Creating Spring Integration Flow Bean");
var pollerSpec = Pollers
.fixedRate(5000)
.maxMessagesPerPoll(1);
return IntegrationFlows
.from(Mail.imapInboundAdapter("imap://username%40domain:PASSWORD#outlook.office365.com:993/INBOX")
.javaMailProperties(myJavaMailProperties)
.simpleContent(true)
.maxFetchSize(1),
e -> e.poller(pollerSpec))
.transform(myTransformer)
.handle(myHandler)
.get();
}
Below are my Java Mail properties:
mail.imap.port=993
mail.imaps.ssl.enable=true
mail.debug=true
Any help for the following questions are highly appreciated:
Is there something missing/incorrect in our config?
Is this basic authentication deprecation by MS causing the issue? https://learn.microsoft.com/en-us/exchange/clients-and-mobile-in-exchange-online/deprecation-of-basic-authentication-exchange-online
If item#2 is true then is there a documented way in Spring Integration Mail to support OAuth2?
