While trying to pass a PCI compliance test, we were in iis7.5 (exchange 2013 CU6) trying to adjust Authentication. We must have changed something that has caused us not to be able to log in to owa. ecp works great. If we type in the wrong password in owa, it lets us know, but when we type in the correct one, we are redirected to the login screen. Any ideas what may be wrong?

Hi,

Try to upgrade Exchange 2013 CU8. I faced this issue, after upgrading it is fine.

Thanks

Riya,

thank you. I will try that as a last ditch effort. This worked this morning, but after some iis modifications in the authentication, it failed. I'd feel more comfortable fixing this before an update.
