Hi, I inherited an Icinga installation, which for the most part if working well, but I've spent far to much time trying to get notifications (emails via M365) working, so rather then spend countess more hours on this, its time to admit defeat and pay someone who knows what they are doing to get our notifications working.  If you have good experience with Icinga, please PM me.  This is a paid engagement.
