If you do not want to renew a certificate at the end of the certification period, you can set it to expire at the end of its term without notification. If this option is enabled for a Trust Service product, renewal reminder emails will not be sent. To use this feature, the Trust Service product status must be Active.

1. In the Control Panel, click Trust.
2. Click the domain that you want to set to let expire.
3. In the Status section, click to put a checkmark in the box beside Let expire without notification, and then click Update.
