Unable to add playbook to automated incident response for Azure Sentinel

[mjamati]

I created a playbook using an Azure Sentinel Incident creation trigger, which shows up as in preview.

I can test everything from the playbook itself: it's able to generate an email and/or slack message depending on the situation.

However, when going to azure sentinel incident rule settings, no playbook show up as available.

I can confirm that if I list all configured playbooks, that one shows an Azure Sentinel Incident (preview) trigger kind.

@mjamati Is the Analytics rule with which you are trying to add the Playbook a custom rule created by you or default one/Fusion Rule built by Microsoft?

For Fusion/Default rule created by Microsoft, you won't be able to attach a Playbook. The feature is currently not in Public Preview.

This is a private preview and can only be accessed through the private preview program.
If you have an active NDA with Microsoft, you could enroll into the program => https://forms.office.com/Pages/ResponsePage.aspx?id=v4j5cvGGr0GRqy180BHbR-kibZAPJAVBiU46J6wWF_5URDFS...
