We're having an issue where no email notifications are sent out when someone is enrolled in a course -- specifically via manual enrollment. For the life of me, I can't find a setting where that would be disabled -- or even a setting where that is explicitly enabled.
When searching through the forums, I do see other similar or related issues and various screenshots that I'm not able to find in our site. For example, https://moodle.org/mod/forum/discuss.php?d=368967 has a screenshot where the manual enrolments config page has an option to enable a welcome email. When I go to the manual enrolments config page on our site, there is no such option.
What am I missing? Is there an additional plugin we need to install or enable in order to have enrollment welcome emails?
