After you attempt to try Hybrid Configuration Wizard between Exchange 2013 SP1 and Exchange online (Office 365), You are unable to login to your OWA/ECP Page and instead you get an 500 unexpected error:
If you go to event viewer You might find Event ID 4 which shows the error:
The HCW or “Hybrid Configuration Wizard” In Exchange 2013 (CU6 or 8) might cause some changes to your CAS folder in the following path and file.
“c:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\ecp\DDI”` the file name is RemoteDomains.xaml and multiply some variables which causes ECP to fail and report that error.

Looking in the path I have wrote above “\Microsoft\Exchange Server\V15\ClientAccess\ecp\DDI” and opening the file that I have mentioned “RemoteDomains.xaml” you can clearly see there are incorrect format that have been duplicated 3 times.
To make sure that this was the cause, I have another server with CU8 on it so I went and checked the same file which was in the same location to find the result different.
This is the server that works in another environment and doesn’t have any issue.
So, the solution was to remove the two duplicates and correct the format of the variable line… I corrected the first line that includes
<Variable DataObjectName=”RemoteDomain” Name=”TargetDeliveryDomain” Type=”{x:Type s:Boolean}” />
And deleted the other two identical lines.. then I saved the file and closed notepad.
Next: Open IIS on the same server and go to “Application Pools” right click on the affected pools and Recycle them.. You don’t need to reset IIS as the fix should work right away.
After recycling checking if the pool is reporting started or not…
