I am using OpenInviter (Version 1.9.6) to import contacts from Gmail, Yahoo, and Hotmail.
All of them were working well last month, but now I am unable to import any contacts from Hotmail.
I am also having problems importing some Yahoo contacts. I tried http://svetlozar.net/address-book-importer-demo.html, but it's giving me the same error for the specific Yahoo contacts that are giving me problems:
Login Failed. Please Check Your Email-Id and Password you have provided
Most of the scripts including Openinviter dont really work properly or sometimes doesnt work at all, relying on such scripts is not a good idea. So i would suggest using oAuth (where available) or specific apis provided by the Service Providers, Like
Hope it helps you in finding some way.
OpenInviter has not kept up with the changes that have been happening to Hotmail/MSN/Live/Outlook.com
