In my outlook i have add my gmail accout if i want add more accouts like rediffmail.&yahoo how i can configure that

What sort of email client or accout are you using? I. E. Gmail, hotmail, outlook, yahoo etc.,

1. reset your password using alternate email id
2. reset your password using security questions

Point your web browser at http://www.gmail.com

If another account comes up, sign out of it by clicking the avatar in the upper-right then clicking "Sign out."

If you then still can't sign in to your account, click the "Need help?" link on the sign-in page.

my facebook accout [email protected]
no open

Go for it. Point your web browser at http://www.gmail.com

go into the account settings and put all your email info in then go into manual settings and put this into the incoming and outgoing servers boxes
Rediff incoming mail server: pop.rediffmailpro.com
Rediff outgoing mail server: smtp.rediffmailpro.com

I forgot my password in rediffmail. I tried to enter many other but do not succeed. I cannot open my account because of the password now I know it but if I enter my correct password also I cannot open My accout in rediffmail

you need to configure pop3 and smtp inorder to use the rediffmail. If you have the pop3 and smtp of rediffmail then configure and things should be fine. Also make sure there are few settings that needs addtional settings like smtp sometimes may require password for outgoing mails this may also be additional setting.

i cant access my yahoo accout ,i hv to verified orkut account ,i think my account expired how to access my that accout

I think you need to check with rediff. You can configure Gmail, yahoo etc. But I doubt about rediff.
