I have migrated from SharePoint 2013 to SharePoint 2019, here I am facing a strange issue, like list alerts are working fine but when I create any alert on any document library, no mails are triggering(means alerts are not working on document library), neither the old alerts that were created in SharePoint 2013 are working in new environment. please suggest what to try
Please check as following:
- Will the same user be alerted in list or library?
- When you set an alert on a specific file instead of the entire library, is it effective?
- Does the alert setting only have no effect in the migration library?
Please create a new library in new server, send alerts on single file or entire library to multiple users to compare the results.
It was resolved by re-registering the alerts, for reference please see point no. 9 in the below link:
