We are trying to get our set up an SMTP function but keep hitting errors with the test email. We even tried both WP-Mail-SMTP and Easy WP SMTP. After talking with our host at WPEngine we couldn’t find any issue on their end since they do use OpenSSL and told us to use port 2525 since we are using Outlook. Our IT department also said that port should work just fine and isn’t blocked by Outlook. I even used another SMTP hostname of premierdisability-com.mail.protection.outlook.com. However, that one gave the same error but said connection Timed Out instead of Network is unreachable.
The only option I can think of is editing/swapping the class-phpmailer.php and class-smtp.php files with an older version. But Easy WP SMTP says it should be compatible with our setup of WP (WP v4.8, PHP v5.6). Do you think that would be a good option to try or know of anything else to try?
