Freescout 1.8.143 Problem Fetching Emails on MS365

[jimmie-jam]

I just set up an Ubuntu Server 22.04 with Freescout 1.8.143 and have everything working except Fetching Emails.

I am using an Outlook365 distribution group for outgoing and incoming (fetch). The outgoing works like a charm, but fetching messages fails with: Error: connection setup failed; File: /www/html/vendor/webklex/php-imap/src/Client.php (391)

I also tried my own email address (still in Outlook365), and my personal Gmail address and get the same error. I do have IMAP enabled for my O365 accounts, so that is not the issue, and my O365 address can Send As the distribution group address I'm using for incoming and outgoing messages, so that should not be an issue.

I'm stuck.

If my Gmail account worked, I would suspect the O365 account setup, but since neither were able to fetch messages, I think it's the FreeScout config.

Any thoughts?

Thanks!
