You can review the expired entries of a list, and extend the expiry time of multiple expired entries.

1. Navigate to the list. For example, Settings -> Blocklist -> Custom Blocklist.
2. Click Review Expired. For more information, see Information in the Review Expired Tab
3. Select the entries for which you need to extend the expiry time. You can select a maximum of 20 entries at one time.
4. Click Extend Expiry Time.
5. In the Extend Expiry dialog box, click Yes to confirm.
   The Expiry Date field for a subscriber is calculated based on the expiry timer value set for the subscriber entries. If the Never Expire option enabled, then the subscribers get an indefinite expiry value. This is valid for all lists.
