How about Apache OpenOffice? http://www.openoffice.org/why/
Plus, it is free. Now to one has to pay attention when downloading and installing it to get rid of the commercials but I have done it on a number of computers. The only thing it does not have is an e-mail model like Outlook.
I know there are good wp programs. It’s just that MSFT doesn’t have one.
Try Mozilla Thunderbird with the "Lightning" plugin. I've sent meeting requests to Outlook users, and it works. It does calendars, notes, and tasks too.
