Question around the Exchange Online TLS 1.0 / 1.1 topic ... is this just for SMTP Auth or connectivity in general? because while i can see EWS traffic in our Service Trust portal reports i cannot see POP3 / IMAP4 client for which i know are using TLS 1.0 (based on WireShark traces).
Hi Jamie, this is for connectivity in general. POP and IMAP are not included in the report, unfortunately because no logging exists that exposes the encryption protocol version used for POP & IMAP clients. To capture this information, you may need to capture network trace logs from your server. See https://techcommunity.microsoft.com/t5/exchange-team-blog/exchange-server-tls-guidance-part-2-enabling-tls-1-2-and/ba-p/607761 for documentation on this.
