Delete User Alerts from SharePoint Site Collection 

SharePoint users often subscribe to the alerts on any lists or libraries of the site. This blog post describes how to remove those alerts from the entire Site Collection. One of the benefits of removing unwanted alerts is that you can protect the mail server from being overloaded.


This is a very simple process.


First open the site and then go to Site Actions and then select Site Settings.

Then select User alerts under the Site Administration category

Then select the user from the drop down and then you will see the list of alerts for that person

Then select the alerts which you want to remove and click on 'Delete Selected Alerts'. Now you have successfully removed the User Alerts from the SharePoint Site Collection.
