Hi guys,Only just started using OsTicket and I like the look of it. I am currently attempting to configure email sending through the admin panel.My SMTP settings are as follows:server: smtp.office365.comport: 25 / 587(TLS)Authentication is not required as the IP address I am using is whitelisted with Exchange online. When trying to connect (either with or without authentication I receive this error:Failed to connect to smtp.office365.com I have verified I can connect to the SMTP server and send mail from my server in a Python script no problems. Which leads me to believe the issue is with either osticket or my PHP setup.Please can anybody advise?Thanks
