Another tool we released last week is the OWA admin tool that Tosh pointed out. It is a set of web pages, so it must be deployed on an IIS server (in the same domain as the Exchange server), but it does not have to be on the Exchange server itself. Using the tool, you can set the OWA configuration registry keys (attachment blocking, outbound charset, etc) on other Exchange servers.

Here's the screenshot of the main part:

And here are some other screenshots for various sections of the page: attachment blocking, themes, segmentation. Tosh's blog entry has the link to the download.
