In the Personal Preferences section individual users can decide whether to receive notifications about their enrollment in or unenrollment from a training plan or course directly in Microsoft Teams (off by default):
After this option is activated notifications will be delivered in Microsoft Teams whether they are triggered from an action in the LMS365 browser version or in the LMS365 app in Microsoft Teams.
Catalog admin still controls which notifications will be sent for a catalog. However, the individual user can decide whether to receive these notifications in Teams as well. Email notifications will not be affected by this option. To learn more about notifications in Microsoft Teams follow to How to get the most out of LMS365 via Microsoft Teams.
