I'm try to bring down the amount of emails sent when scheduling downtime.

Yesterday, I needed to schedule several hundred services for downtime as a major scheduled deployment of code was going to require many services to be restarted.

Prior to scheduling the downtime, I went into Admin-->Notification Management-->Notification Options to remove Host Downtime & Service Downtime from all users/groups. I applied the above settings to all users and contact groups. I then proceed to schedule the downtime through the Hostgroup commands function. Nearly blew up Exchange with the several thousand emails it sent out...

So I'm wondering if there is something I've missed or this is possibly a bug where unchecking the Host & Service notification isn't taknig effect.

It would be great if there was an option to instead send one email for a bulk scheduled downtime. I'd even consider blasting this to the entire IT team, similar to how we send out change notifications. I guess I'll write up a feature request for this.

Are your contacts mostly configured as XI users, or core contacts?

They are all XI users. I then build contact groups with those users and apply them to hosts/services.

I tend to not apply individuals to hosts/services.

The settings you changed there are user notification options only, you will need to go to your contact, or contact group and remove the options for downtime alerts there "CCM > Alerting." That should do the trick!

In the CCM and Legacy CCM, I'm seeing the "S" checkbox blank on all contacts that I updated through the process explained above. This should prevent scheduled downtime notifications, correct?

It depends. Do you have any other boxes selected for "Notification options" (w, c, u...)? If you have something selected and your "s" box is cleared out, you shouldn't be receiving the notifications when scheduled downtime starts and ends.

Note: Options set on a host/service level will override the template. If you haven't set up notification options on a host/service level, you will have to check the notification options set in the template that you are using. There may be a few layers of templates in place, so it could be easier to disable notifications about scheduled downtime on "per user basis".

Yes, D, U, R, F are all checked, for all contacts.

What about the service notification options, the above are host options.

W,U,C,F, _ R, _ are checked.

If you log in as one of the users that received these downtime notification, click the username top right, click "Notification Preferences"

Are the downtime check boxes still selected?

if not, I would go to
CCM -> contacts -> edit -> Alert Settings Tab -> Manage Host Notification Commands
CCM -> contacts -> edit -> Alert Settings Tab -> Manage Service Notification Commands

and see what handler you have selected
