Thanks for looking. I suspect the problem is before this at the authdaemon stage. I guess trying to strace authdaemon might help but getting W8.1 and Outlook and a similar not-so-busy test server set up is not going to be easy.
The fact that you proved that turning off SSL is a factor pretty much eliminates anything authentication-related as a possible cause. You're unlikely to get any useful results by logging authentication requests.
The most likely explanation is that MS-ware is now requiring valid CA-signed certs from IMAP and SMTP servers. Previously, they did not validate their certificates.
So, either MS-ware does not recognize the CA authority you got your certs from, or the chained cert is not set up correctly. If your problem is solved by turning off SSL/TLS, those are, pretty much, the only two possibilities.
Try reversing the order of the intermediate cert and your cert, in the pem file. Also, verify that the commonName in the cert matches your server's hostname. And, of course, the cert hasn't expired.
