Disable Email Alerts at WebApplication Level In SharePoint 2013

In one of my recent technical panel discussion on SharePoint 2013, there comes a interesting question from an enthustiastic chap on disabling email alert at web application level. So we found a way out to do this at the web application level.

$weburl= Get-SPWebApplication "http://msyite/"
$weburl.AlertsEnabled = $false
$weburl.Update()

In a similar way, we can enable the alerts at the web application level.

$weburl= Get-SPWebApplication "http://mysite/"
$weburl.AlertsEnabled = $True
$weburl.Update()

Happy SharePointing :-)
