#2507 – web.config problem

As soon as I started using the web.config I now can not log into my Outlook web access

My website is

http://www.xxxx.com

My Outlook web access is

https://xxxx.com/owa

here is my web.config

I can pull up the OWA signon page but I get a 403.18 error when I try to loggon

Please help

I turned off sh404SEF url optimization (now set to no) and still can not sign-in to outlook.

If I rename my web.config back to web.config.txt I can sign into outlook fine but then only my home page of my website is accessable...

I believe I have solved this by adding the following to joomla rule 2

<add input="{HTTP_HOST}" pattern="xxxx.com" negate="true" />

Which appears to stop it from trying to rewrite my calls to OWA and allows OWA to work normally again...

No I did not, I hunted around and read various questions and reply's about the web.config file until I understood the way it worked.
