You will need the Full Write Groups permission to perform this action. The permission must reach every campus of the group, and a group available to All can only be deleted by someone with no campus limit.
From the left-hand navigation menu, click Groups and locate the group you want to delete.
Delete from the Groups listing
Click the three-dot menu next to the group's name and choose Delete.
Delete multiple groups at once
Select the checkbox at the start of the row for each group you want to delete.
Click the Bulk Actions button that appears above the table.
Choose Delete from the menu.
Note: If you select a group you can edit but not delete, the whole delete is refused and the message tells you why. Groups you cannot edit at all are skipped and counted.
Delete from inside the group
Open the group, click the Actions button in the top right area, and choose Delete.
Confirm the delete
Warning: A confirmation prompt appears whichever method you use. Type Delete into the field and click to confirm. This action cannot be undone.
Groups with subgroups
If the group has subgroups, the prompt also lists them and asks What should happen to the subgroups?
All subgroups should no longer have a parent. - keeps the subgroups and removes their link to the deleted group.
Delete them all (including any subgroups) - deletes the subgroups along with the group.
If you delete a group together with its subgroups, only the subgroups you could delete yourself are removed. The rest stay.
Tip: In some cases, deleting a group may not be possible because other records rely on it, or because it sits at a campus you cannot reach. When that happens, deactivate the group instead. Open the group, click Actions > Edit group, toggle the Active? field off, and click Save. Inactive groups are hidden from listings by default but remain in the system, and you can filter to show them again at any time.
