SQL Server Reporting Services (SSRS), when integrated into SharePoint 2013 enables reports to be sent to users via email. From the report click Manage Subscriptions.
If you’ve not configured SSRS you may receive an error in the Application Event log on the SharePoint server hosting the SSRS service application. This could take the form:
The Report Server Email extension failed to read its configuration settings from the rsreportserver.config configuration file. The extension is not available to users. (Application: SQL Server Reporting Services Service Application, CorrelationId: …)
The web page may also fail to load, with an error like the one below.
If you encounter this error, open the SQL Server Reporting Services Service Application from Central Administration. Next, open e-mail settings and configure the SMTP server. Finally, open Provision subscriptions and alerts, enter the appropriate account details and click Ok.
