## Delete an RCOS

Deleting an RCOS that is in use by mailboxes causes all of those mailboxes to be assigned the default (1) RCOS. A warning message is displayed to allow you to cancel the operation. If you are deleting the default RCOS, the mailboxes assigned to it will be assigned to the next available RCOS. You cannot delete the last remaining RCOS in the system; therefore, you cannot select all RCOS for deletion.

To delete one or multiple RCOS:

1. In the Restriction COS list, select one or multiple RCOS, and then click Delete. The system will prompt you to confirm the deletion.
