In the 7.5 Release, the ability to email a report to a url has been enabled.
In the 7.5 release, you can select to email your reports via a url. This enables your users to access and view their scheduled, emailed reports via a new application, called the Report Viewer.
If your users select the email url option, they will receive a url in their email. When they click on the email, it will bring them to the location of their report within the Report Viewer application. The user can then download, save or print the report.
This is an excellent option to use for large reports that you do not want to send thru your SMTP server.
