I work in production support and daily I get an email stating that all is OK. If I don't get the email then maybe there is an issue with my SMTP server or my application not sending emails. Opening and reading an email that says all is OK is repetitive and can be missed.
I would like a rule to run daily at 10 am to check for the absence of the all OK email today. This way outlook will alert me with a popup if our system is not sending emails out.
