Hi,

My Sage accounting system used to send invoices with no issues and then stopped working for a second time. The first time I had to change the configuration of the SMTP server which had fixed the issue for several months. Now it doesn't send emails again.

I have confirmed that the settings have not changed. The only security option is the torn on SSL/TLS or not with a check mark. The setting are as follows:

Why did it stop working (around end of Nov.) ?

Outlook | Windows | Classic Outlook for Windows | For business

    I did some tests this morning. MS is bloquing my emails that have a subject line like this: "Client Quote 4470 from Garage S. Beauchamp" or "Client Invoice 4470 from Garage S. Beauchamp"

    The way I verified this is I sent 2 identical emails except the subject line from my hotmail account, I received the email with "test email" but not the quote subject line. Can I get unbloqued ?

    Do you have the latest version of Sage? It looks like StartTLS support is the problem.

    I just tested and managed to send email. It could be a Network issue at your end. It can also be an issue with TLS version as we only accept TLS 1.2 now. A network capture should be able to tell you the actual reason (Network or TLS version)

    @heartburn(2)") - When connecting to port 587, it's must to use TLS encryption using STARTTLS Verb (POP, IMAP, and SMTP settings - Microsoft Support). So this error is expected. If you want to connect using Non TLS, you can use port 25.
