Why are my scheduled reports generated but are not getting delivered by email?


NFA 9.1/9.2/9.3


Sometimes the email server cannot cope with the number of scheduled emails/reports requested to run at the same time.

You will probably see an error such as below in your ReporterAnalyzerManagerServiceLogdate.log
This log should be located at; Install location/NFA/Reporter/Logs

14:02:00 2 - Report Scheduler: Error executing report: ID 123
14:02:00 2 - Report Scheduler - :
Service not available, closing transmission channel. The server response was: #4.x.2 Too many messages for this session
Affected recipients xyz
at NetQoS.Email.Smtp.TransformEmailer.InternalSendEmail(String emailAddresses, String replyTo, String subject, String message, SmtpAttachmentSources sourceType, Object source, String attachmentName, String mimeType, UInt32 emailId)
at NetQoS.Email.Smtp.TransformEmailer.SendScheduledEmail(IEmailScheduleItem scheduleItem, String mimeType)


Check your schedule, it's possible you may have quite a number of reports to send at the same time, if they are large reports, or even if they are not, try and spread the them out to run over a longer period of time.
For instance if you have 10/20 reports/emails scheduled at 1am, separate them into smaller batches and perhaps for 1am, 1.30am, 2am.
And see if this resolves your issue.
