OWA email on Insinct s30

here is what I had to do to get my instinct s30 working with my corporate owa email.
Using my browser I went to the login page and then removed everything after the /auth/
I then opened the instinct email to add the work account and typed everything from the url of my browser.  Below is what my browser url was.
https://webmail.mycompany.com/exchweb/bin/auth/
After that I just used my login name and password and it works.
(obviously I changed the .mycompany.com to hide my real employer)
