Virto Calendar App roles and permissions

There are two levels of permissions that are relevant to Virto Calendar App.

**First level:** [The permissions of the SharePoint site](https://docs.virtosoftware.com/docs/calendar-overlay-pro/administration-and-system-requirements/user-permissions/first-level-sharepoint-permissions-settings/index.md) itself, set by the **Site Administrator** for user groups / specific users. Virto Calendar App inherits these permissions.

**Second level:** [The Virto Calendar Overlay permissions](https://docs.virtosoftware.com/docs/calendar-overlay-pro/administration-and-system-requirements/user-permissions/second-level-virto-calendar-app-permissions-settings/index.md), whereby you can assign a user as a calendar manager who can modify calendar settings. Please go to the subpages to find out where to find these settings and how to configure them.

At the moment, when the **Tenant Administrator** selects “[Consent on behalf of your organization](https://docs.virtosoftware.com/docs/calendar-overlay-pro/installation-and-configuration/authorization-and-permission-request/index.md)” and authorizes Virto Calendar App, calendar permissions are the same for all users.
