I have just installed this application in place of Windows Live.
I have to say that it is very good and easy to set up.
In fact I was considering to upgrade to Microsoft Outlook, but there was no point once em client was installed. I did try other free applications but it was not as impressive as em client.
If there was any cons, I was concerned when my computer warned me that the “Publisher” was unknown prior to install. This caused me to steer well away at first but after a security scan found nothing to worry about.
Go for it. It is excellent!
