First, despite the Premium command, the product disappeared in the meanders of the Chronopost distribution. This software from a few grams can so easily fall off the truck (!!). In short it took 2 weeks instead of 48 hours to receive a replacement order! So not respected contract! Installation is easy and fast, however, has everything to alienate the user and lock in the Microsoft sphere! This is very annoying! Additionally Outlook 2013 does not accept previous versions immediately and it is necessary to have a pst file recovery tool to read previous versions of messages. In short, despite the quality ... painful !!
