PaulC.27959 (DigitalFish, Inc.) asked a question.
I recently added the Microsoft 365 Integration to Okta. Everything (SSO at Microsoft, Office 365 provisioning) is working fine. However, Microsoft Azure sends me multiple emails a day titled "Your identity synchronization from on-premises is unhealthy," saying there was a lack of synchronization attempts from the "identity synchronization tool."
All information I can find about this assumes we have an AD on-prem server, but we do not. Our users are defined in Okta (or in most cases, Bamboo HR). There's nothing to sync with! Is anyone else using Okta Microsoft 365 integration without running an Active Directory server? Does anybody know how to stop this warning?

Hi @PaulC.27959 (DigitalFish, Inc.) , Thank you for reaching out to the Okta Community!
I was looking into this and it might have something to do with the "Manage Security defaults" setting on the Azure side. It could be that it erroneously expects an on-premise integration.
If your authentication and Provisioning with Okta works, but you are just receiving notifications from Azure, you might want to check those settings.

I've also found a mention of something similar here:

If my answer helped, remember to mark it as best to increase its visibility for other members of the Okta Community who might have the same questions as you.
Hope my answer helps!

Mihai, That seems like a reasonable theory. I turned off Security Defaults (a single option) in the Azure portal, which I didn't know existed! (I use the Microsoft 365 admin portal). We'll see if that stops the emails. The old thread did sound a lot like this, and it sounded like it just went away that time. Thanks!
