"simple, fast, free and it works!"
Small rize, simple interface, opens quickly all winmail attachments generated by Outlook. It's one task only, but if if you use Thunderbird you just cannot see those kind of Microsoft stuff.
Well, the only con I see is that is a single-task program, but anyway is small and free...
