Bounce Processing with Office 365

ℹ️ Support
1

Has anyone come up with the correct settings for using office 365 for bounce processing. We know these are correct:
$bounce_protocol = ‘pop’;
$bounce_mailbox_host = ‘outlook.office365.com’;
and that the correct port is 995 but not having any luck with any of the following:
$bounce_mailbox_port = ‘995/pop3/tls’;
//$bounce_mailbox_port = “995/pop3/ssl/novalidate-cert”;
//$bounce_mailbox_port = ‘995/pop3’;
//$bounce_mailbox_port = ‘995/pop3/notls’;

Phplist displays this error: Cannot create POP3 connection to outlook.office365.com: POP3 connection broken in response.

Any help or suggestions greatly appreciated!

More verbose output should tell you what response Outlook is providing, and allow for further investigation into what is “broken” about it.

Thank you. It must have been a transient issue as it is working now. The setting that worked for us was: $bounce_mailbox_port = “995/pop3/ssl/novalidate-cert”;

POP is not working, did I make a config mistake?
