I have three accounts that I access on my W7 pc using  WLM  ... Outlook account, Pop3 account and a Gmail account.

I set up my WLM Contacts originally (I guess associated with the then Hotmail/ now Outlook account) and use this listing on my pc when sending emails to any of my 3 accounts from the pc WLM.

However, I now have purchased an Android tablet and Android smartphone and want to ensure that this single Contact listing is shared and updated across all three devices. How can I achieve this please? 

Thanks Ron
