    RPC usually uses its own protocol (TCP Port 135 IIRC) but this is rarely opened to the internet.
    Outlook Anywhere (RPC over HTTPS) uses port 443 (a standard open port) to communicate with the Exchange server, which will “unwrap” the https packets and pass the contents onto Exchange.
    This blog gives a reasonable explanation: https://blogs.technet.microsoft.com/exchange/2008/06/20/how-does-outlook-anywhere-work-and-not-work/ otherwise you could assume it is the fairies (or gremlins) inside Windows which are responsible :)
