Hi I followed Tom's suggestions in publishing Exchange 2003 OWA with ISA Server 2000. (Followed the 5 part tutorial articles). Using SSL bridging. Also use OWA forms-based authentication. When I type the URL in my browser I intermittently I get a HTTP 400 Bad request. The only reference I found at Microsoft was KB article 300707. I am using IE 6 SP1 Will it fix this.??
