What are the user privileges required to for an ssrs report owner to 'send email' Yes, this question is a duplicate to:
  SSRS - rsAccessDenied error but that question is 2
  years old and unanswered...so I thought I might try again.


Our DBA has recently departed leaving behind a number of SSRS report subscriptions to which he is (or was) the 'owner'. Based on the advise found at Changing the SSRS Subscription Owner I have created a new domain account, assigned that domain account full privileges on the SSRS server (at least 'for now') and yet I am still getting the error message: 


  Failure sending mail: The permissions granted to user 'DOM\NewUser'
  are insufficient for performing this operation.Mail will not be
  resent.


What privileges, in SSRS, SQL Server and/or Active Directory are required to allow "NewUser" to send email.
Is the new user allowed to send mail on the SMTP server?

You can do this:


Review this and make sure your setup is valid with the correct user (MSDN Link).
Also check the settings in RSreportserver.config (MSDNlink).
