I'm about to update 300 items in a list that I know lots of users are subscribing to (notification by email on every item update event). I've tried turn this off by using STSADM:
stsadm -o setproperty -url http://[SITE] -pn alerts-enabled -pv false
as well as by using powershell:
$webappurl="http://[SITE]" $webapp=Get-SPWebApplication $webappurl $webapp.AlertsEnabled=$false $webapp.Update()
The notifications are still sent out by email. What am I doing wrong?
