Unable to log in bsnl broadband email account in outlook express.

I am facing a problem receiving and sending emails in outlook express using bsnl broadband and bsnl broadband user ID.
I am repeatedly prompt for password. I am entering correct password every time, but failed to receive or send the emails.

I am receiving this error message:

"There was a problem logging onto your mail server. Your Password was rejected. Account: 'nmma.bsnl.in (1)', Server: 'nmma.bsnl.in', Protocol: POP3, Server Response: '-ERR invalid user name or password.', Port: 110, Secure(SSL): No, Server Error: 0x800CCC90, Error Number: 0x800CCC92

Please resolve my problem.

Were you facing same problem earlier or you are trying to set it first time ?
