Review for Owl for Exchange by Edgar Koster
Rated 5 out of 5 stars
This indeed does what I expect, sync my mailbox etc. Two nice things I can't find yet though:
1. Download all mail button. I've a new account added with owl and want all my emails downloaded when adding an account
2. The checkbox ' save reply in same folder' is disabled when using an account linked with owl.
