Hasn't worked in any 6.5 build I've seen so far. In fact, I don't think Microsoft has updated the Pocket Outlook app in any significant way in a
very long time, which bugs me a lot... the calendar sync/integration with my Exchange server is the primary thing I use this for, and it can't even do simple things like show colored categories to match Outlook. I wish Microsoft would start paying more attention to replicating as much Outlook 2007 functionality in Windows Mobile as possible rather than mucking about with all this Titanium interface stuff. I don't need things to look prettier, I need them to
work.
There's only one app I've seen that will do colored categories -- AgendaOne:
http://www.developerone.com/agendaone/
It doesn't do it out of the box and requires a bunch of configuration by hand because it uses its
own category color assignments rather than pulling them from Outlook, but it does work. Problem is it's a pretty heavy app and wants to take over your contacts and other stuff too... meh.
