Benefits of Using a Microsoft 365 Shared Calendar and a Group Calendar

Group Calendars are suitable for larger departments or groups. Microsoft SharePoint and Teams connect better with this type of calendar. Finding events in group calendars is quite easy. Shared calendars enable users to give permission and options for sharing access to individuals. 

The group calendar is tailored to address the requirements of a specific group of users. On the other hand, every user with permission has access to managing events. This helps in making task management in Microsoft 365 better. The owner of the shared calendar has complete control over the permissions and the visibility of the calendar.
