TLS 1.2 outbound SMTP?

TLS 1.2 is supported. But it's not EspoCRM, but your environment is responsible on a protocol version that will be used. It's unlikely that your env does not support 1.2.

Because we make use of Office 365, it is important that the TLS level is at least 1.2. Since microsoft is going to depreciate TLS levels 1.0 & 1.1 soon: https://docs.microsoft.com/en-us/mic...o365-worldwide

So we need to know how Espo sends its emails and what TLS level is used.

Can you explain what you mean when you say TLS 1.2 outbound SMTP ? Usually, Mail Server with SSL certificate is also responsible for connection.

When sending mail via outbound SMTP, can anyone confirm that the TLS level is 1.2?
I could not find this in the documentation.
