Mail is not sent every time by swiftmailer using office365

Question

Smtp details which we use are correct, for host smtp.office365.com mail is not sent every time.

Sometimes this error is generated, Fatal error: Uncaught Swift_TransportException: Failed to authenticate on SMTP server with username "XXX" using 2 possible authenticators in vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/Esmtp/AuthHandler.php on line 181

Observed behaviour

Sometimes with the same details, emails are sent.

Expected behaviour

It should send an email every time.

Can anyone please tell me what should I do?

Is the login credentials you used correct and the.env file configured correctly? Here are two links that might be useful to you.

Yes, everything is correct. Mail is sent sometimes. But fails most of the time. – Hasmukh Mistry Sep 07 '18 at 08:09
