f-damodio Yes. The scheduled task just runs cron.php, which will process any automated actions in the system (not just polling email, but anything else you have set up such as overdue tickets, etc...). Once you configure email fetching, this will then be included in the list of tasks cron.php executes.
(depending on how you have the system set up, make sure the scheduled task is using the same PHP 8+ version as the web server)
