Anyone from microsoft outlook mobile backend team? Software there seem to fail to recognize letsencrypt.org issued certificates used for imap (and possibly smtp, too - can't test because it complains about imap first).
On my side I see "sslv3 alert certificate unknown: SSL alert number 46" which is indication of certificates not being recognized. htbridge.com/ssl test recognizes these certificates just fine (it can test imap service directly) So likely the problem is on outlook mobile backend servers.
