Mailer - Email for Case Creation

I am unable to get the email to create a ticket feature working with an Office 365 mailbox. I have proper credentials, however the Trudesk logs says Logon Failure for Imap. I have followed the instructions. The Trudesk instance is on a digital ocean cloud droplet, on Ubuntu. I have ensured that in addition to port 8118, I have port 993 open in both directions in case that was an issue. Any suggestions would be appreciated.

Here is the latest log entry:

Might be related to OAuth 2 in Office 365:

Authenticate an IMAP, POP or SMTP connection using OAuth | Microsoft Learn

Does anyone know if Trudesk supports this OAuth 2?

It does not. You will need to use Legacy Auth for Office 365.
