How can an administrator remove a shared Dashboard created by an inactive user?

To remove a shared Dashboard created by an inactive user, reactivating the user and then deleting the shared Dashboard is the correct approach. When a user who has created content, such as a Dashboard, becomes inactive, that content may still be accessible but cannot be modified or deleted because of the user's status. By reactivating the user, you restore their ability to access and manage their shared Dashboard, allowing the administrator to delete it as needed.

The other options do not effectively resolve the issue. Deactivating the report used in the Dashboard will not help, as the Dashboard itself isn't directly tied to the liveliness of the report alone; it's about the user's access. Deleting the Dashboard from an active user's account doesn't apply here, since the Dashboard is linked to the inactive user, making it inaccessible for deletion. Lastly, contacting support is a potential last resort, but it is better to reactivate the user and delete the Dashboard directly, as it offers a more immediate solution.
