OWA fails with FBA off but OMA works and vice versa

If Forms Based Authentication is off, then OWA fails but OMA works. When I enable FBA, OWA works and OMA fails. Obviously I need both to work but can't seem to noodle out the correct combination. I have Require SSL unticked and Basic/Windows Authentication ticked under the Virtual Directories in IIS. All was working fine a couple of days ago, it just started failing for some reason. Any insight would be appreciated.

Update: Currently OMA is functioning and OWA is giving a proper login screen and then after credentials are ented, displays a HTTP 500 error. I posted that very issue as a question on Friday and the fix turned out to be turning on the Forms Based Authentication and setting the compression to High. I was extremely glad when I saw that this indeed fixed the OWA HTTP500 error, but what I did not realize until late last night was that when FBA was enabled, it broke OMA.

Thankfully it is the weekend and users are not really needing the OWA, so I have left FBA unchecked to keep OMA alive. Any help would be appreciated.

Simply re-running the CEICW on SBS should fix this.

Otherwise refer to the article Shree has posted and go down to the section where it mentions the exchange-oma directory and the ExchangeVDir registry setting.

After running the CEICW, confirm everything is fine, if not then confirm your settings are as per the article.

Hi, thanks for the tips. Everything seems to have gone well after following the KB articles steps but now a new problem has come up. OMA is working fine as well as the normal functions of Exchange, local Outlook connections etc. but now when attempting to login to OWA I receive a 440 Login Timeout error message. I was not getting this error before so the issue has changed. Any idea as to what may have caused this behavior?
Thanks.

turn off FBA press apply then turn it back on again

make sure "require SSL" is unticked on the Exchange-OMA directory

Cycled the FBA and verified that SSL was not enabled on the Exchange-OMA directory. Still getting the 440 error on OWA and OMA is still working.
