How to add other employees calendars
Go to the Calendars section.
Open the list next to the Add button. You can add a Company/User/Workgroup calendar. Select the type from the list and choose a color.
If you have added a calendar, but you do not see an events, ask its owner to configure access permissions to calendars. Permissions must be at least View availability and names.
How to make my calendars visible for other users
Open your calendar menu and choose Edit.
Specify appropriate access permissions for colleagues to be able to add your calendar. Permissions can be assigned to the departments, workgroups, and users.
Your events will appear in your colleagues' calendars.
The employee who added your calendar will only be able to see all scheduled events, but won't be able to edit events in your calendar unless you give permissions.
If necessary, you can also remove the calendar from the list.
