Hello friends!
I want your help to resolve the error message below when I try to create a migration endpoint in Exchange 2016.
Error received when terminating hybrid Configuration wizard:
HCW8078 Migration Endpoint could not be created.
Microsoft.Exchange.Migration.MigrationServerConnectionFailedException
The connection to the server 'myserver.com' could not be completed. Microsoft.Exchange.MailboxReplicationService.MRSRemoteTransientException
The call to 'https://myserver.com/EWS/mrsproxy.svc' failed. Error details: Access is denied..
Microsoft.Exchange.MailboxReplicationService.MRSRemotePermanentException
Access is denied.
Checks performed:
Opened ports in the firewall;
active MRSproxy;
Permissions set correctly for the EWS directory;
All updates applied on Windows and Exchange;
Admincount set to zero;
MSExchangeServicesAppPool recycled and IIS restarted;
There is no migration endpoint created, so it's not a credential issue;
I did the connectivity test on https://testconnectivity.microsoft.com/ and the result was success without errors.
If anyone has any guesses and can help, I'd be very grateful!
I need to find the light at the end of the tunnel, because this problem is taking my peace.
