How do I modify Calendar permissions?
Go to Calendar.

Select the Calendar tool from the Tool Menu in your site.
Select Permissions.

Modify the permissions for the roles listed.

- Select the checkbox for each permission you would like to allow for a given role. (Deselecting a checkbox will remove the corresponding permission.)
- Select Save to save your changes.
Note: You may see different roles listed depending on the roles which exist in your site. A role must be present in the site in order for you to modify its permissions.
