Thunderbird/sunbird
Thunderbird I use and it's good. Not used sunbird but memory tells me it does the calendar bit.

I use Thunderbird for my personal mail account
but if I were a business user I wouldn't be able to put up with it's limitations.

Not that I disagree, I don't use it for business
but I'm curious which limitations.

I'm sure it's down to me not needing to use it very much and therfore not bothering to learn how it works
but I just find it harder to use and for some reason it appears to have eaten my archive of old messages, fortunately they were just calender reminders.

I find the constant updates annoying
But that could just be me.

That said, I've just discovered that you can export messages as individual files
rather than relying on Outlooks annoying .pst format.

Hmmmm, this might require looking into further.

Thunderbird also allows you to manage several email accounts at once
Usually good at auto-detecting the settings for work email and gmail these days (though hotmail reminds a dysfunctional nightmare in this respect)
