Servidor: mensaje 22051, nivel 16, estado 1, línea 0The client connection security context could not be impersonated. Attaching files require an integrated client login
The user 'rpp' is a SQL Server login.
You must use a login mapped to a Windows account - also known as an 'integrated client login'.
Sending mail requires that the server act on behalf of the login, this is only possible with a Windows login - SQL Server logins cannot take part in Windows impersonation.
