I've never used it - I have to use the shiiiiiiiite Novell Groupwise here at work - what a pile of poo!
Our company just switched from GroupWise to Outlook about 6 months ago.
consider yourself lucky, most employees (myself included) miss GroupWise. I was much more productive in Groupwise than OutPoop. I think the biggest problem with Groupwise, isn't GroupWise itself but how companies deploy it; most companies castrate it for some reason (I'm guessing laziness being the primary reason)
of course I am always happy at home with my mac mail.
Does anyone know if the To-Do's in Mail 3 will be shared with iCal. To-Do's seem to be a bit of an item that would cross the boundries of the two apps.
EDIT: about the question above, sorry I shoulda read ALL of the forum posts before asking, looks like it has already been answered, sorry & thanks.
