User role as recipients for email

I'm working with the OP on here. The schedule is set up (annoyingly changes per day), and the parameters are configured in Data. We've narrowed it down to the following errors. However, we're not able to address items 3, 4, or 5 (as called out by Transistor above). I'm assuming this built-in user roles function on the report module works in v7.9 (yes, I know). As you can see in the circled areas, everything seems to be verified. We've also played around with the ReplyTo User Source (#4) and still get the same error. The manual calls this out as Optional anyway.

We do e-mail reports from this server.

There are users with valid e-mails associated with this role. It's just the two of us until it's proven.

Has anyone been successful with using this function? We saw a similar posting referencing system.report.execute, but I'd much prefer to handle everything "locally" rather than trying to reference external scripts and such.
