Sync Hotmail/Outlook.com contacts with the Thunderbird address book.

For as long as I have been using Thunderbird there have been those folk who wanted to synchronise contacts with Hotmail/Outlook.com.  This has been relatively simple for Google account holders, with multiple add-ons available, with relative strengths and weaknesses.  Whilst chasing information on an unrelated subject in the past week I stumbled upon the TZ Push add-on. Something of an unfortunate name as it does not allude to it's ability with activesync or Outlook.com.  This add-on connects to ActiveSync data sources. The add-ons page states Z-Push, Zentyal/Zarafa, Horde, Outlook.com and other Activesync providers.  So there are two things here.

1. TZ Sync is an activeSync address book synchronisation tool. So any service that offers activSync or Exchange ActivSync should be supported.
2. There is a truly viable way to syncronise contact information between Thunderbird and Outlook.com.
