OWA Broken, No Email inbound or outbound after installing MSCRM Email Router

Installed MSCRM Email Router on same machine as the CRM installation
Exchange server(2007) on seperate machine.
Exchange edge server(2007) on seperate machine.

Confiugred Email router on CRM server.
Tested Email router received errors in testing

Mailbox not found (access test succeeds)

Symptom: When you click Test Access in the E-mail Router Configuration Manager, the test succeeds. However, you receive HTTP 404 errors in the application event log when the E-mail Router processes e-mail messages. Check the IIS logs for the following error:

Request Filtering: Denied because URL doubled escaping 404.11

Resolution: Run the following command on the Exchange Web site to allow double escaping:

%windir%\system32\inetsrv\appcmd set config "Default Web Site" -section:system.webServer/security/requestfiltering -allowDoubleEscaping:true


Obtained the above statement from http://rc.crm.dynamics.com/rc/regcont/en_us/op/articles/tshootrouter.aspx


Ran the above command in the exchange management shell on the Exchange server
Now cannot browse web / ping / tracert from the exchange server.
Cannot email to the outside world. Internal emails work

Ran
 %windir%\system32\inetsrv\appcmd set config "Default Web Site" -section:system.webServer/security/requestfiltering -allowDoubleEscaping:false

Unistalled MSCRM Email router

Still not working.

Want to give a try by changing the appcmd command:

Go to Start -> Run ->cmd-> cd \windows\system32\inetsrv
C:\windows\system32\inetsrv> appcmd set config /section:requestfiltering /allowdoubleescaping:true

firewall was blocking me but still OWA wont work.
I recieve an error when I attempt to browse the owa from the IIS on the Exhange.
https://127.0.0.1/owa
"There is a problem with this website's security certificate."

Below is the the links to
Click here to close this webpage
Continue to this website(not recommended)

If we click the continue to this website link we get
Internet Explorer cannot display the webpage
   
   Most likely causes:
You are not connected to the Internet.
The website is encountering problems.
There might be a typing error in the address.  

Re-installed OWA still the same any suggestions.

Yes we are using SSL
ON E2k7 console, change the internal URLs to have http:\\FQDN-of-server\owa
On IIS, DWS and \OWA v.directory remove the "Require SSL"

Then try checking the same using http:\\servername\owa
