Hi, We are doing an OWA implementation with Exchange 5.5 and I wanted to find out if anyone had used IIS 5.0 for this. I've read that it can be done, but had problems with the install. Can anyone recommend any white papers on how to get OWA to work with Exchange 5.5 and IIS 5.0? Any help would be appreciated. Cheers, Alex.
