Disable all notification contacts but one

[jkinning]

Well...that defeats my purpose. I didn't want to remove them but just disable them temporarily but I guess I'll have to remove them in order to deactivate them.

Either that, you can edit them and just disable the Host and Service Notification option for each contact.

Is there a way to do that in bulk?

If the contacts do not have the notifications enabled directly but are inheriting them from a template, you can edit the template and that will change all of the contacts the template is applied to.
Other than that, you would have to manually edit them.
