Hello Experts,
I'm having a hell of a time trying to migrate my Exchange 2010 to Office 365.
I get error/warning HCW8078 - Migration Endpoint could not be created when running the Hybrid Configuration.
I get error "We coun't detect your server settings. Please enter them. The Exchange Remote endpoint settings could not be determined from the autodiscover response. No MRSProxy was found running at "mydomain". When I enter the FQDM of my exchnage (same FQDN my OWA runs on) I get an error.
I followed the document below with Microsoft support team at least 3 times already.
https://hblogs.technet.microsoft.com/exovoice/2016/09/19/troubleshooting-issues-where-the-migration-endpoint-cannot-be-created-in-hybrid-scenarios/
I have also disabled, enabled MRS and restarted the IIS several times. (This is something that has worked for several people). But not for me.
My MRS Replication is working, and health is ok.
My firewall is directing traffic coming to 443 to the CAS.
The last (Test Migration Availability) I ran gave me the results: "The connection to the server "FQDN of my CAS" could not be completed. ) (The remote server returned an unexpected response: (405) Method Not Allowed...).
Microsoft support keeps saying the firewall is somehow blocking traffic but I everything looks good when it comes to the firewall.
I honestly don't know what else to do. Any support is greatly appreciated. My goal is to migrate current users to Office 365, once all there then decommission the Exchange 2010 server.
FYI:
My auto-discover is running on a .com domain and my FQDN on a .net domain. (Not sure if the problem is somewhere in IIS).
Regards,
Nelson
