This is, well, pretty simple. While OWA, in my opinion, is awfully damned nice (1) it doesn’t look terrific in anything but Explorer, and, (2) it’s functionality is kinda crippled in anything other than Explorer. There is, however, a fix for Firefox. Download the “IE2tab” plugin (something like that – that isn’t the correct name) and, using the tools menu, add the URL of your inbox to the thing…..it, then, works almost perfectly and displays fine. Using Chrome or Safari…? As far as I know, you’re screwed.
