Jeff commented on CAMEL-18623:
------------------------------
Yes, as you see from the example posted in the issue description above I am
using a custom authenticator bean named `exchangeAuthenticator`. I pass the
OAuth access token as the password, as shown in the Groovy snippet below.
{code:java}
@Component
class ExchangeAuthenticator extends MailAuthenticator {
@Autowired
ExchangeTokeCache tokenCache
@Autowired
ExchangeConfigurationProperties configurationProperties
@Override
PasswordAuthentication getPasswordAuthentication() {
def accessToken = tokenCache.getToken().accessToken
def user = configurationProperties.username
return new PasswordAuthentication(user, accessToken)
}
} {code}
I have confirmed that I am getting a valid token from the authorization server,
and that the user name is also valid according to the [exhange OAuth2 for IMAP
docs|https://learn.microsoft.com/en-us/exchange/client-developer/legacy-protocols/how-to-authenticate-an-imap-pop-smtp-application-by-using-oauth].
I can also see from the debug logs (also above) that OAuth authentication is
being attempted.

> Project: Camel
> Issue Type: New Feature
> Components: camel-mail
> Affects Versions: 3.18.2
> Reporter: Jeff
> Priority: Minor
> Fix For: 3.x
>
>
> Camel mail component does not appear to work with OAuth2. This seems clear
> from the lack of documentation or unit tests regarding OAuth2, but having
> spent a few hours trying different approaches it seems like the reason it
> doesn't work is that it isn't supported. So maybe this is a new feature
> request if the mail component is indeed not intended to work with OAuth2. If
> it is intended to work with OAuth2, and there is some evidence of this,
> please be so kind as to direct me to it. I would be happy to update the docs
> if this is the case.
> Here is the component for reference:

> {code:java}
