Hi all,
Some of our mail servers are old doesn't support SMTP-TLS.
We note this notes about enforcing TLS 1.2:
https://support.microsoft.com/en-us/help/4057306/preparing-for-tls-1-2-in-office-365
Does it mean Office 365 doesn't accept inbound mail from external mail servers not talking TLS after 31 Oct 2018 ?
I'm unable to find any official document.
Would anyone please help ?
Thanks a lot
