Review for LookOut (fix version) by rpg
Rated 3 out of 5 stars
This really meets a need because of the annoying Microsoft Winmail.dat attachments.
However, it still has some blemishes. The most important one I have found: you can "save all" the attachments and that works (at the cost of dumping useless chaff into your filesystem), but you can't save individual attachments that were buried in a winmail.dat. For whatever reason, that does not work.
