Exchange O365 hybridation wizard issues

For our Exchange migration to Office 365, I'm trying to complete the hybrid wizard of Exchange 2013.

During the wizard it starts some HrcClient processes (HrcClientv3.5.exe and HrcClient.exe):
Right after that, the last step before it fails is the OAuth authentication configuration:
OAuth authentication

Then I get the error
Exchange Hybrid Configuration
An error has occurred.
The error has been reported for further investigation
If I take a look at the log created on my on-prem Exchange server, it shows no error:
[11/12/2015 16:10:46]    INFO : Engine execution complete, exiting.
[11/12/2015 16:10:46]    INFO : Session=OnPrem Total Cmdlet Time=28.9662936s
[11/12/2015 16:10:46]    INFO : Session=Tenant Total Cmdlet Time=21.9789242s

Any help or guidelines would be appreciated

You are trying to run Hybrid Setup from Office 365 portal?

You should run it from your Exchange 2013 EAC not Office 365. later on the Exchange 2013 hybrid wizard will ask you to login to your Office 365 portal.

Hi Mohammed

No, I start the hybrid wizard from the EAC.
When I click Modify to start the hybrid wizard, it does ask for Office 365 login, then the URL switches to by itself

That's strange! It doesn't happen with me ... have you enabled WSSecurity on EWS and Autodiscover ?
You need to enable them and enable MRSProxy on the Webservices too

Get-WebServicesVirtualDirectory -Server Servername | fl Identity,MRSP*,WSS*
Get-AutoDiscoverVirtualDirectory -Server Servername | fl Identity,MRSP*

Post the results here please.

Here are the results:
[PS] C:\Windows\system32>Get-WebServicesVirtualDirectory -Server serv-exch2013 | fl Identity,MRSP*,WSS*

Identity                 : SERV-EXCH2013\EWS (Default Web Site)
MRSProxyEnabled          : True
WSSecurityAuthentication : True

[PS] C:\Windows\system32>Get-AutoDiscoverVirtualDirectory -Server serv-exch2013 | fl Identity,MRSP*

Identity : SERV-EXCH2013\Autodiscover (Default Web Site)

It seems I don't have MRSProxy for AutoDiscover

I've opened a discussion on Technet's forum.

They suggest to upgrade our on-prem exchange to CU10, and verify our OAuth config

I'll post results here

There is a new wizard since september.

I was able to complete the hybrid wizard with it.
