Bonus! Unhealthy MEMCM Clients email report

Bonus!

As another example of how you can export data from MS Graph, below is an Azure automation Runbook you can use to generate an email report of unhealthy co-managed MEMCM clients. Specifically, it will export a list of MEMCM co-managed devices that have synced with Intune in the last 7 days but have not synced with a MEMCM management point in the last 7 days. It will then send you the list as a CSV attachment in an email.

Unhealthy MEMCM Clients runbook

Requirements

• Your automation account must be using a managed identity

• The managed identity must be granted the appropriate permissions to Microsoft Graph as described in this guide

• Outlook 365 with direct send or smtp relay configured
