If an organization is no longer needed, it can be deleted. However, if your organization has projects associated with it, the organization cannot be deleted.
If you need to keep the projects, ensure you have backed up (exported) the organization's projects before deleting the organization.
To delete an organization, follow these steps.
From a project page, click the See Available Projects button. This opens a menu showing all organizations and projects that you can access.
Select Overview to open the Organization Overview page.
Locate the organization you want to edit and click the Gear icon.
On the Edit Organization page, click Delete Organization.
Confirm you want to delete the organization in the Confirmation dialog.
