Thanks and regards,

What do you mean by "get my account information"? Usernames and passwords?

Interfacing with Hotmail is pretty much impossible. Have you looked if these services provide a web service API?

Actually i want to retrieve the information from yahoo,google or hotmail account. I will take user name and password as input and after submission of this i want to display the information(e.g. name,country,phone number etc.). I also want to display all of my friends email address from my address book.

I have seem this feature in some applications where you give you email id and it would get you your addressbook from that email account.

I guess this is the way they do it .The email service provider might be exposing a service for this purpose and the application uses that.
