In Beta 1 it was possible to enable the Calendar Service to automatically change the Sametime Status if you are joining a meeting.
If I open the preferences dialog in Beta 2 and navigate to this settings page, I will get an empty page. Here is my screenshot:

The preference page
Any idea?

I’m getting the same thing in Beta 2. I’d really like to get it back! I miss it now that I’ve become used to having it.

There’s no place in the settings screen to put a user name and password like there used to be but it works now!
