Scheduled reports are not sending out to users on specified time. I checked the report delivery details and everything looks good. Anyone know what would cause this issue?

I had this happen to me earlier this year and the specific problem we had to fix was that the file being sent out was an XLS and it was a very large file, being sent to a job role. At this point, two solutions presented:

1) we could change delivery file to XLSX, or

2) we could keep the XLS and instead of a job role, send it to a real name/s.

I do encourage you to go to the helpdesk though, if this doesn't solve your problem.
