I brought a new server 2008 into our SBS 2003 environment. We finally have it up and running with message flowing for Outlook and cell phone users. When we go to the website https://
<ourdomain.com>/owa the site comes up and we can enter our username and password. When we submit this, the next page that comes up is completely blank except for two words in the upper left corner saying: Bad Request. So there's obviously a disconnect between IIS and Exchange and it probably simple but I'm not that experienced in IIS/Exchange setup and troubleshooting.
