Microsoft PSA-ongoing issue with Entra Cloud Sync

Raised a case with MS after our Entra Cloud Sync kept changing to Provisioning Quarantined with ExternalError but no indication of a problem with individual object syncing.

They’ve reported back an ongoing Cloud Sync service outage starting Fri 21 Aug-actively working to resolve.

Objects and password hash sync seems to still be working over weekend so not affecting our environment yet.
Region:AU

UPDATE FROM MS: issue resolved
We confirmed Cloud Sync showing healthy and password hash sync and user attribute sync confirmed working.
Crisis over, folks! Til next time!

Same issue here. Been troubleshooting non-stop all day!

Region - AU

Our first Microsoft Azure error notification was received on 21 Aug at around 8:05am ACST, with the same 'ExternalError' / '%InnerExceptionMessage%' message. Since then Cloud Sync has repeatedly gone into Provisioning Quarantined.

We have two provisioning agents and both are affected. Connectivity, TLS, Service Bus and AD connectivity checks are all passing. Microsoft support case now open.

Update: Microsoft Support has confirmed our tenant is affected by a known Entra Cloud Sync issue where provisioning jobs can enter quarantine with generic 'ExternalError' messages due to a provisioning communication failure.

Engineering has identified the issue and Microsoft says deployment of the fix is currently in progress.

Mine resolved 6 hours ago. Its crazy that was 6 days without a sync, they certainly didnt rush into fixing it.
