I made a FRESH install of OsTicket on the newest stable version, on centos 7. My company uses an exchange 2016 server.I've confirmed, and TRIPLE confirmed the login credentials, and i still get the error :Can not authenticate to IMAP server: AUTHENTICATE failed.I've tried both SSL, and non-ssl connections, both with IMAP and POP. Have confirmed the ports are open by telnet. I'm at a loss and the documentation here got me this far. Any help is appreciated.
