Reviewing expired alert definitions

Once an alert definition has expired, no additional alerts will be generated unless you modify the expiry date. You might want to reactivate an expired alert definition if the alerts are still required.

There are two ways of finding out which alert definitions have expired:

In the Database Explorer, expand Alert Definitions. Expired alert definitions are listed with a gray icon.
In the Alerting dialog, click Expired Alert Definitions to list the expired alert definitions that you own.

As the creator of these, you can do any of the following:

Change the expiry date, for example to make an alert definition active again.
Change the actions that are being monitored.
Delete the alert definition - this will not delete the alerts that have already been sent (or that are in the process of being sent).
