I hope someone can help.
We have a stuation where some of our customers generate reports and sends us an auto generated email on the successful completion of the report generation. As this happens at 3 times during the day 6am, 12pm, 4pm we need to monitor a mailbox for NO email delivery during certain time periods. 6am - 6.20am, 12pm - 12.20pm & 4pm - 4.20pm. So if we don't receive an email during these times an alert email is generated and sent to a distribution group.
we are currently running Exchange 2007 on Win2008 server.
Just to make things interesting this mailbox may receive 3 emails out of 4. We therefore need to be able to determine what email is missing and send an alert to that fact.
