Recently I was looking for team organizer. I thought that KOrganizer would be good sollution because it has structured tasks.

I'm satisfied with KOrganizer as personal organizer, but now i'd like to use it for team work. And I have two questions:
1) what alternative for korganizer is for windows? with feature of strustured tastks
2) what is the easiest way to sync korganizer with other korganizers and alternative clients?

There is a beta version of Kontact for Windows available here:

For sharing the probably best solution is to ue some kind of server, e.g. a groupware server like Kolab.

Other form of remote resources might work as well, e.g. ical Calendar file on a webdav share, etc.

Cheers,
