I must admit I haven't used 7.32 much as I've been taking some time off from
programming out of hours so to speak ;-)

Interesting - My git repo and Visual Studio build is up to date but I will
give it a go with the released version of 7.32 first to see if I have any
problems against Exchange with imap and imaps.

Out of interest what SSL provider were you using? You mention a Visual
Studio build of libcurl so I'm guessing either OpenSSL or SSPI (SChannel).

Cheers - But for your sake I hope that was a test account.

Whilst you masked out your user details from the command line you included
them in base64 with the "AUTHENTICATE PLAIN" for the world to see :(

If it was a real account I would suggest changing your password ;-)

Kind Regards
