Exchange Hybrid Configuration Wizard - Error 1603 - Connector registration failed

[Eric Fuentes]

Did any of you encounter this error while installing hcw on an exchange server? 

Here is the event viewer error details: 

Connector registration failed: Make sure you are a Global Administrator of your Active Directory to register the Connector. Error: '"The registration request was denied. "'

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.

[#4]

Can you be more specific ?

[#5]

DNS is good. How do you suggest checking the GUID?

[#6]

@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??

[#8]

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?

[#9]

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?

[#10]

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.

@griffom7Does anyone have an idea?

[#12]

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.

@Eric Fuentes 

Hi,

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

@PhilippV 

Hi,

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

[#15]

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