Dedicated Hybrid App: temporary enforcements, new HCW and possible hybrid functionality disruptions
Hi The_Exchange_Team !
Y ran the following script .\ConfigureExchangeHybridApplication.ps1 -FullyConfigureExchangeHybridApplication and everything finished apparently OK. However, I don't see any sign in logs for the app: https://learn.microsoft.com/en-us/Exchange/hybrid-deployment/deploy-dedicated-hybrid-app#auditing-exchange-hybrid-application-usage-in-entra-id. It doesn't show the successful logins from your network to the new service principal. Also, I validated OAuth Connectivity Status and see the old appId: 00000002-0000-0ff1-ce00-000000000000. What could be happening?. Something strange is that when I run the Get-AuthConfig command, I notice that the ServiceName parameter shows the AppId of the shared application and not the new one.
Is this normal? Should I update it manually?
Thank you very much!
