Just to clarify...
Safari 4 does not install on 10.5.7 but to install software and to run software that already exists on the machine prior to upgrade are two different things.
Safari 4 runs on 10.5.7 just fine if you installed it before you upgraded.
The biggest reason at the moment that I don't think Safari 4 installs into 10.5.7 is that the Safari 4 Public Beta installer contains a component that checks to see which version of Mac OS X you're running. Since this Public Beta installer was released just before 10.5.7 it's possible that the installer just doesn't recognize it as a valid build (just a theory). The same would go for 10.6 which (if memory serves me) didn't even let you install dev builds of Safari 4. I forget
For the user that said it didn't work on 10.6 Snow Leopard...ALOT of things won't work on it, the current seeds are still tagged as previews and I'm not positive they are even considered Beta stage yet.
For people with Outlook Web Access issues in Safari... it must be either browser settings or the deployment of OWA that's the issue. I'm able to log into my webmail at mail.microsoft.com just fine (even the E14 builds work).
