I have a new installation of osTicket that I'm having trouble setting up to send e-mail. Here is our configuration information:
osTicket Version v1.10.4 (035fd0a) — Up to date
Web Server Software Microsoft-IIS/10.0
MySQL Version 5.7.23
PHP Version 5.6.38
When I try to send a test e-mail, I get the following mailer log in the system logs:
Unable to email via php mail: (e-mail addressed removed to protect the innocent) mail() returned failure
We are trying to send through an Office 365 e-mail account, which we do just fine through another osTicket that we set up some time ago on a Linux/Apache server. On this new installation, everything looks good on the "About this osTicket Installation" So I'm just wondering what I'm missing. Can you help me?
