OWA Issues

$

Hello,

I am experiencing several symptoms of what is probably a single problem, though I can't be certain of that yet. Any help is appreciated.

My environment: I have two DC's running Server Core 2012. I have one Exchange Server 2010 SP3 server that I'm migrating from. I have two new Server Standard 2012 machines with Exchange. One is a CAS and one is Mailbox. I am receiving and sending e-mail just fine at this point. I have plans to add two more exchange servers for redundancy but I want to fix this issue first.

I've moved mailboxes and everything worked fine with migration. The point where I started having issues is when I started to implement Spam filtering. I used Install-AntispamAgents.ps1, configured IPBlockList with spamhaus and spamcop, configured InternalSMTP server with appropriate IP address, and configured content filtering.

I also changed IP addressing of the exchange servers. I suspect this may be where the issue is as it seems like I'm not getting a good connection between Mailbox and CAS server.

After the above configuration I went to verify all of the setup was still working and noticed my phone would no longer sync, OWA was not working and ECP was no longer working.

Symptom 1: I cannot access OWA internally. I can get to the website https://mail.domain.com/owa (internally) or via https://ex04.domain.com/owa. However, I get the Windows Integrated log on prompt instead of the nice form. When I try to log on it fails even though username/password are correct. I copy and paste them so I know they are correct. I have been able to get to the forms log on page as well in troubleshooting. When I get there and try to log on I get "The user name or password you entered isn't correct. Try entering it again." This is not the case, I've tried typing and using LastPass to autofill correct information that works elsewhere.

Symptom 2: I cannot access OWA externally. When I go to https://mail.domain.com/owa I get error 404. I'm pretty sure that DNS is good as if I go to https://mail.domain.com then I get the IIS 8 page. I suspect something is not right between front end/back end servers and proxy.

Symptom 3: ActiveSyn doesn't work on Android client. It did previously work and then it quit after I started implementing spam filtering.

Steps I've taken:

It seemed strange to me that the spam configuration would suddenly kill OWA and ECP. I tried removing the InternalSMTPServer and verify incoming/outgoing mail and that still works. OWA/ECP has been a process of recreating virtual directories and trying various combinations of authentication methods. I haven't found the right one yet.

I have been trying to follow the technet and KB articles I can find, but it seems there is not a lot of information on this issue with Exchange 2013.

Can someone shed some light on what is going on and what steps I might try to solve this?

Here are some of the references I've been using:
