Hi. I'm thinking in migrating from Office 2003 to OpenOffice, and I want a good replacement for Outlook. It has to have excellent IMAP support. I'll probably use Thunderbird, since I use it when I'm under linux and I also use the portable version, BUT I'd like to know if there are other good/better options for IMAP. Also, I'd like an app that handles calendar and tasks. Maybe I'll try Sunbird. Are there any other FREE options out there? I know there is a Evolution version for Windows now. Please comment WHY you feel an app is good or bad.
