If someone set up your account for you, obtain your password from that person.

If you attempt to forward a decrypted message without first encrypting it, Messenger reminds you to encrypt it.
You see warnings about message tampering only when an incoming message has been altered in some way after it was sent. Alteration of the original message content can mean corruption due to mishandling or interception and forgery.

To access your mail server, you may need to enter your user name and password. If you don't know them, review your account information provided by your site or Internet service provider.
