Can I set a email alert when my exchange 2010 is hitting 30 emails are in-queue, it may can reflect my Exchange is getting some problem, like cannot sent out email. If I could, where can I find that option? Thank you.
Currently I am using Kaseya 9.2
You can look if one of the perfmon counters referenced here is available on your exchange system to track this:
There should be some sort of counter that has this information or you may be able to get it from one of the KNM Exchange templates.
