I was just checking the notifications sent when items are created from emails, and I change the checking time to a smaller value e.g. 2 minutes. But this had no effect, it still checked with the previous time. I waited for about 15 minutes and it still didn't check at all, let alone the 7 or so times it should have checked within that time.
Do I need to restart one of the services on the server to get this change to be applied?
