Sync error mail issue

Question

Hello Microsoft Team,

reference case- https://learn.microsoft.com/en-us/answers/questions/1192777/set-alert-for-azure-ad-synch-error-for-every-succe

I am facing a different issue. while sync is on hold or server was down.

i can see a warning triggered under "Microsoft Entra Connect Health > Sync services"

My Email configurations looks good.

But, Under "sync errors" i don't see any data. and did not receive any mail for the same.

I am Not sure why the alert was not here under Sync Errors and why did not receive any mail. I understand from your previous ans that to reduce the volume of mails in 24 hr it triggers. but, why the initial was not triggered?

Thank you,

Parthasarathi

Hello Parthasarathi Panda

Thanks for contacting MS Q&A. I will be able to help you with resolving your issues.

The key thing to understand is that “Health service data is not up to date” is a data‐freshness alert raised by the Connect Health agent, not an object-level sync error. That’s why:

It doesn’t show up under the Sync errors blade. The Sync errors page only surfaces object-level failures (duplicate attributes, validation failures, federated domain changes, etc.) in the synchronization engine itself

Docs - https://learn.microsoft.com/en-us/entra/identity/hybrid/connect/how-to-connect-health-sync

The “Health service data isn’t up to date” alert has two severities: Warning: Some data types haven’t arrived in the last two hours—no e-mail is sent. Error: No data has arrived in the last two hours: This does generate an email to your configured recipients.

You saw the Warning state, which, by design, does not trigger the built-in notification e-mail.

Docs - https://learn.microsoft.com/en-us/entra/identity/hybrid/connect/how-to-connect-health-data-freshness

To receive the alerts: • You’ll need to build your own Azure Monitor alert on the Connect Health metric (for example, on “SyncDataFreshness” or the heartbeat metric) and point it at Action Groups of your choice or If you only care when the service is completely stale, leave the built-in notifications on, and you’ll get an e-mail when it escalates to Error.

That should explain why you didn’t see it under Sync Errors and why the initial warning didn’t generate mail.
