I have two CAS/HUB/MBX servers, a test mailbox on server 01 but if I try to access OWA on 01 I get the 500 error but if I access it off the 02 server my mailbox pulls up. &nbsp;I've compared the security of web.config on each server and the permissions are the same. &nbsp;I also did 'Reset Virtual Directory' on the server I'm having an issue with but did not have any luck, I'm still getting the error. &nbsp;Any other thoughts?<br />

Thanks,<br />

I am having the same issue. When I turned off the friendly errors I get just a blank page after the login.
