I wont waste any time on whether I think themes are an appropriate use of dev time when they are so many unresolved issues mentioned already. As a forced early adopter (we have many mac clients using entourage - if you didnt know already that causes your streaming and EDB files to go crazy which is supposed to be gone in 2007) there are quite a few issues with OWA light.
- no way to enable read, delivery receipts, nor do they work if set globally from a PC client and then use OWA light
- no weekly calendar (monthly isnt there on either I know)
- GAL searching isnt alphabetical with more than one page of results
- GAL searching for Groups dont yeild all results with more than one page of results
- no way to see your whole system folder list (that dropdown is a joke and nearly impossible to use if you have many folders)
