Sorry for the noob question. Do i need to create a connector in Exchange online to receive emails from the internet ? :) Also for outbound connector to the internet (all domains) what is the recommended TLS settings ? Below is what i currently have configured. The connector is currently disabled.
#1 No, by default, all emails are received by what could be described by a default connector applying to all messages. You would create additional connectors to treat segments of your inbound traffic differently. #2: For all messages we do not recommend enforcing the use of TLS because it will lead to some messages not getting delivered. Very few organisations do that for all messages. Instead they identify important partners who they wish to enforce TLS for.
