Hello Ally,
Just got back from talking to the host.
The server does not support OAuth 2.0 for SMTP authentication. OAuth 2.0 is handled on the Microsoft 365 side.
He said, use Microsoft 365’s own SMTP relay or API-based sending (Graph API), not the server’s SMTP service.
Remember that only the IT guy has access to 365.
What can I do on my end, if any?
What customization is possible with your script, if even possible.
Thank you very much.
