I am trying the Incoming Email setup in Jira Server using OAuth integration suggested by JIRA server.
While creating a mail server, I am able to Authorize with OAuth but on selecting the Test Connection i am seeing below error.
Unfortunately no connection was possible. Review the errors below and rectify:
- AuthenticationFailedException: AUTHENTICATE failed.
I have added the snippets.
When I tried with "Authentication method" as Basic Authentication, it worked for me. But I see a message as below. Am I missing something here?
This mail server uses basic authentication. This method is planned to be deprecated by Microsoft and Google. Update the authentication method to OAuth 2.0 to keep receiving mail. We recommend selecting OAuth to authenticate to this mail server. Basic authentication using only a password is planned to be deprecated by Microsoft and Google. Learn more
