I believe that the guys developing the "evolution" mailer were working on some tools to interface to the Microsoft Exchange, including the calendar features. I have no idea where that stands (but I'd love to know). Please someone.
FWIW I *HATE* OutLook. Which brown-shirted micrsoftie dictated that everyone must use the upper left corner of the page for favorite folders - I don't have favorites and I want this prime screen real-estate back. Why do I have to play games to see the actual headers ? The mail-sort features are arcane and ill conceived. Conceptually I like the calendar, but it's not intuitive. The screen layout seems to be fixed, and the app column to the left of mail-header column to the left of message means the message text region is too narrow. Font defaults bite it right off - readable but frilly and annoying.
We've been creating an internal web tool for project and account mangers to request consultant time. What we want to have is something that will allow users to submit calender updates to consultatnts once all is confirmed and aprroved. We are all using Outlook calender (not my choice).
convince them to use google calendar haha. Take the easy road I don't know of any apps that use python for web stuff. Some of the open source CMS's may be a way to look. Maybe Joomla, Drupal...Thats all php based tho.
