Modern HCW (Hybrid Agent): troubleshooting like a pro

Hi Mirela_Buru ,

I hope you can help with this issue:

I have tried installing the HCW in Exchange Server 2019 and other member server but still I encountered the same issue above.

Here's the HCW logs:

2022.12.16 19:58:43.391 10333 [Client=UX, fn=SendAsync, Thread=23] FINISH Time=220.0ms Results=NotFound {"error":{"code":"Application_NotFound","message":"Application 'd28373ea-2a38-4d5d-90a6-cc3dd3a9aaa4' not found or OnPremisesPublishing is not enabled for your tenant.","innerError":{"date":"2022-12-16T19:57:58","request-id":"37de6d5d-21e1-4921-b136-2a3698d12da4","client-request-id":"37de6d5d-21e1-4921-b136-2a3698d12da4"}}}
