Email Form within X-Corporation skeleton

Was wondering if you have any good info or way to troubleshoot a contact form. My in progress page is here:
I did set up a test Mailtrap account to see if the form posted correctly, and I tried to use our Office 365 SMTP settings, and still can’t get the email form to submit. It is using the “contact.html.twig” file and the email admin plugin. Looked at the log files and didn’t seem to show much detail. Any ideas are greatly appreciated.
