How to disable SharePoint 2013 alerts using CSOM

Question

Using CSOM, I am able to retrieve the collection of alerts for a SharePoint Online site and disable each alert using the following code:

This doesn't work for SharePoint 2013 Server though. I get the error: "Field or property 'Alerts' does not exist".

Can this be done with SharePoint 2013 Server CSOM?

Hi @g h ,

SharePoint 2013 On-Premise CSOM Web object didn't support Alerts property.

Please use SharePoint Server Object Model below instead:

     using (SPSite site=new SPSite("http://sp/sites/MyDev"))  
            {  
                SPWeb web = site.OpenWeb();  
                SPAlertCollection alerts = web.Alerts;  
                foreach (SPAlert alert in alerts)  
                {  
                    alert.Status = SPAlertStatus.Off;  
                    alert.Update();  
                    web.Update();  
                }  
            }  

Thanks
Best Regards
