How to remove inactive Exchange Hybrid Agent if the local server does not exist anymore

Question

Hello, i have the problem, that in our exchange hybrid environement there is an orphaned Exchange Hybrid Agent which i cannot remove. The agent is inactive because the old exchange server it belonged to does not exist anymore. Various tries with powershell show the problem:

Now when i try to remove the inactive agent with powershel, i get the 404 not found error:

The active agent is running on an Exchange 2016 server and is running fine. The inactive agent was running on an older Exchange version where the local server does not exist anymore. How can i remove the inactive agent? Regards, Jan

Hi @Dowidat Jan ,

Please try using one of the following options and check if it can help:

• Run the following Remove-AzureADApplicationProxyApplication command:

  Remove-AzureADApplicationProxyApplication -ObjectId <application GUID> -RemoveADApplication $true
  

• Run the following command to get the application GUID, and then run the Remove-AzureADApplicationProxyApplication command to remove the application:

  Get-AzureADServicePrincipal | where {$_.Tags -Contains "WindowsAzureActiveDirectoryOnPremApp"} | fl AppId, DisplayName
  

Reference: Can't register a Hybrid Agent in Exchange Server.
