1 month ago Hi @TTTPOB, those requests are interesting, they don't look familiar to me. Mox is expecting a request for /autodiscover/autodiscover.xml. I suspect microsoft has started using a new autodiscovery mechanism. A quick search doesn't turn up any documentation. I've been looking at https://learn.microsoft.com/en-us/exchange/architecture/client-access/autodiscover?view=exchserver-2019, which mentions the autodiscover XML file.
Could you try Microsoft's own exchange autodiscovery connectivity testing tool at https://testconnectivity.microsoft.com/tests/O365Ola/input? It's not working for me at the moment (gets stuck at "loading").
Btw, microsoft autodiscovery has never worked in my testing. All their HTTPS requests were failing because they were doing TLS handshakes incorrectly (trailing dot in SNI hostnames, if I remember correctly; the Go TLS library correctly rejects it, other TLS libraries probably not (what nginx is using)). I've only seen Thunderbird successfully use microsoft's autodiscovery.
Perhaps microsoft's new autodiscovery mechanism/code would work with us. First step is figuring out what the protocol is. (:

when type in my email address (me@xx.yy) in outlook, it starts to loading and loading and loading.
I can say the dns are all set, and I can see logs both from nginx and mox nginx
mox
I think my tls/nginx reverse proxy setup are also good because I can log into the webmail and admin page.
let me know if you want more message.
thank you for this great mail server!
