Hi @DE
Thank you for posting this in Microsoft Q&A.
I understand that you’ve put in a lot of effort to set up Graph Change Notifications with Azure Event Hubs, only to encounter an unexpected limitation-Microsoft Entra External ID does not support user change notifications. I understand how disappointing this can be. Apologies for the inconvenience.
As of now, the Microsoft Graph API change notifications feature is not available in Microsoft Entra External tenants.
You can find a list of available features in Microsoft Entra External tenants here: Microsoft Entra External ID - Supported Features
Unfortunately, there is currently no workaround for enabling this feature in Microsoft Entra External tenants.
I would request you to please share the feedback on our feedback channel https://feedback.azure.com/d365community/forum/22920db1-ad25-ec11-b6e6-000d3a4f0789Which would be open for the user community to upvote & comment on.
