We recently had a customer complain that they weren't getting notifications for an issue. The request participant on the same issue received the notification and when the customer checked his spam filter and had his internal IT dept check their email relays, the notifications were no where to be found.
After digging around in the SQL tables (we're on service desk server) we managed to figure out that the customer clicked on "Don't Notify Me" for the 2 issues that he wasn't getting notifications on.
While we do have DBAs who can check the tables if something like this happens in the future, their time is precious and we don't exactly want to waste it on something like this. Is there some other way that we can check to see if a customer has clicked "Don't Notify Me" without digging into the SQL tables?
