Hi, Recently Microsoft changed the way emails are send using TLS1.1, I upgrade java and it work for about a week and now its having issues again. Does any one know of a way to fix it? 12:04:40 PM EmailNotificationProfile[Email\_SMS] [[hostname=smtp.office365.com](http://hostname=smtp.office365.com),port=587] Error sending message to user ‘usr-prov:default:/usr:XXX’. javax.mail.MessagingException: Could not connect to SMTP host: [smtp.office365.com](http://smtp.office365.com), port: 587; nested exception is: javax.net.ssl.SSLException: Unsupported or unrecognized SSL message at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:2211) at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:740) at javax.mail.Service.connect(Service.java:388) at javax.mail.Service.connect(Service.java:246) at javax.mail.Service.connect(Service.java:195) at javax.mail.Transport.send0(Transport.java:254) at javax.mail.Transport.send(Transport.java:124) at com.inductiveautomation.ignition.alarming.notification.email.EmailNotificationProfile$EmailTask.run(EmailNotificationProfile.java:343) at com.inductiveautomation.ignition.alarming.notification.email.EmailNotificationProfile$3.run(EmailNotificationProfile.java:196) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: javax.net.ssl.SSLException: Unsupported or unrecognized SSL message at sun.security.ssl.SSLSocketInputRecord.handleUnknownRecord(Unknown Source) at sun.security.ssl.SSLSocketInputRecord.decode(Unknown Source) at sun.security.ssl.SSLTransport.decode(Unknown Source) at sun.security.ssl.SSLSocketImpl.decode(Unknown Source) at sun.security.ssl.SSLSocketImpl.readHandshakeRecord(Unknown Source) at sun.security.ssl.SSLSocketImpl.startHandshake(Unknown Source) at sun.security.ssl.SSLSocketImpl.startHandshake(Unknown Source) at com.sun.mail.util.SocketFetcher.configureSSLSocket(SocketFetcher.java:626) at com.sun.mail.util.SocketFetcher.createSocket(SocketFetcher.java:400) at com.sun.mail.util.SocketFetcher.getSocket(SocketFetcher.java:238) at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:2175) … 11 more ---

Unfortunately in the [other cases I’ve seen this](https://forum.inductiveautomation.com/t/14945-email-still-using-tlsv1/28051) here and in support the ultimate resolution has required upgrading to 7.9.18 or 8.x which have special options on the email notification profile to force the use of TLS 1.2. ---

Can confirm. 7.9.18 works with Office365, earlier does not due to lack of TLS1.2 support. ---

Well my solution for right now until the customer upgrades was to setup the Windows Server that is hosting Ignition to be an SMTP relay server. Ignition Email Notification → Local SMTP Server → Office365 SMTP ---

I’m in a situation where I need to do just that, but have no experience setting up a Local SMTP Server. I’ve installed hmail on the local machine with Ignition install. Do you know what settings I need to put in Ignition and hmail to make it a relay server for [smtp.office365.com](http://smtp.office365.com)? I’ve tried several settings with no luck. ---

Windows 10. I think I ultimately got it working on a non-production system, but then updating Ignition version helped with my original issue.
