Here is the event viewer error details:

Hello, I'm facing the same issue, my customer has an Exchange 2016 and we have : Connector registration failed: Make sure you are a Global Administrator of your Active Directory to register the Connector. Error: '"The registration request was denied. "'
Exchange is up to CU 22.
Thanks for the help.
Could you please do a DNS check and a GUID check.
DNS is good. How do you suggest checking the GUID?

@Eric Fuentes I have the exact same problem at the moment. "The registration request was denied".
If using an Azure AD user which do not have Global Administrator access the error is: "The registration request was denied. Details: User is unauthorized".
It seems as if the issue is with Azure AD services denying to register the connector, as it can see if the users is a Global Administrator or not...

Michael, i tested this with a non GA account and you were right, USER is Unauthorized came up.

Now the next question is what service or how the service can be allowed for registration??
Yes, it must be some Azure AD services denying access - but which?
Do you know where to find the msi log files from the installer - perhaps they have more detailed information, other than just the generic error 1603?
Hello,
I have the same problem at a customer for 2 days. I use the GA user.
Would it be possible that there is currently a problem in Azure?

I have the same problem:
Invoking powershell script from path 'C:\Program Files\Microsoft Hybrid Service\RegisterConnector.ps1'
Error while invoking powershell script: 'System.Management.Automation.CmdletInvocationException: The registration request failed. Make sure you are an administrator of the AD directory you are trying to register the Connector with.
Folks, I never got a clear answer but the solution we did was to install HCW on a member server running on Windows Server 2019.

Hi,

I have a 2016 member server, I can try again on another member server.

Hi,

I have deployed a Windows Server 2019 as member server with Exchange HCW with success. Thanks for suggestions

@griffom7 I agree, my setup on a member server on 2019 was also successfull :)
