To expire or deactivate an alert:
Click Next Block to move from the Header block to the Date field of the Alerts block.
Query or use the arrow keys to locate the alert you wish to change.
Type an Expiry Date in the Alerts block using the MM\DD|YYYY format. To deactivate an alert, type in today’s date using the same date format.
If the alert has been verified, editing the expiry date cancels the verification. The Verified ? field changes to No (unchecked).
Click Save.
