Hi @dirkdigs ,
What't the version of the Exchange server?
Could you connect the Exchange management shell in on-premises Exchange server normally?

According to my research on the error information you provided, I found there are many reason could caused this error.
1.Please check the Windows Remote Management (WS-Management) service are running, you could also try to restart this service.

2I see you mentioned that you have checked IIS and checked the bindings for hostnames. What is your configuration? Please right-click Default Web Site, and then click Edit Bindings. If a binding exists for HTTP, clear the host name value.If no binding exists for HTTP, create a new binding that has no host name and a value of All Unassigned for the IP address. Finally restart the IIS.

3.The following is the authentication method of Powershell in "Default Web Site" and "Exchange Back End" in IIS.

4I did some research on similar cases and found that this issue can be caused by having IPv6 enabled on the server. Please try to following the article to set prefer IPv4 over IPv6.
Please refer to: Guidance for configuring IPv6 in Windows for advanced users

In addtion, whether there is a firewall in the environment. If it exists, please make sure that ports 5986 and 5985 have been opened, and the policy set by the firewall will not prevent normal communication.
For more informaiton: Installation and configuration for Windows Remote Management

There is a similar case you could refer to: The WInRM client sent a request to an http server and got a response saying the requested http url was not availabe.

Hi @dirkdigs ,
What’s the version of on-premises Exchange server?
Do you means that there is no “Exchange Back End” in the IIS in your environment? So is there any problem with the function of your on-premises Exchange server?
Based on my knowledge, Exchange2013 and above version will have the "Exchaneg Back End" site by default. If there is no "Exchange Back End" site, then the Exchange server will not work properly.

this is still not working . Can you tell me what source IP address Microsoft/Office 365 uses to connect to the exchange server on tcp/443?
I believe tcp/443 is not open on the firewall protecting this exchange server.

Hi @dirkdigs ,
Please refer to this article: Office 365 URLs and IP address ranges
In addition, please note that in addition to port 443, such as port 25, 587, please also keep open.

Have you also checked the "Exchange back end" site? As mentioned above, the disappearance of the back end site is not a normal phenomenon.

Hello this is Exchange 2010 version , So i guess it is normal not to have this in IIS?

Hi @dirkdigs ,
Yes, you are correct. If your environment is Exchange 2010, then there is no "Exchange Back End" site by default.

Hello Do I require a 3rd party SSL certificate for hybrid agent to work as well?

Hi @dirkdigs ,
Do you want to deploy Modern Hybrid?
According to the Micorosoft's official article, we could know that for hybrid agent, we don't need the Third-Party Certificate Required. But for the Autodiscover and transport, we need.

And SMTP doesn't traverse the Hybrid Agent and still requires a public certificate for mail flow between Microsoft 365 or Office 365 and your on-premises organization. SMTP traffic is out of scope for the Hybrid Agent.
