Your computer has password-protected certificates for your user name. You cannot set a new password unless you know your existing password.
If someone set up your account for you, obtain your password from that person.
If you forget your password, you cannot access your certificates or decrypt new or saved messages. Your certificate issuer cannot give you a replacement certificate, so you must obtain new certificates.
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.
Return the tampered message to its sender. Tell the sender you are having problems with his or her encrypted or signed messages.
Contact your system administrator or help desk. Report the incident and inquire about established procedures.

Use the bcc (blind carbon copy) field. All email addresses that you put in the bcc field are hidden from recipients you enter in the To and cc fields. You must always put at least one address in the To field for this to work, even if it is your own email address.
The bcc field is accessible through the To pull-down menu.

The mail and newsgroup server names are probably incorrect. Ask your network administrator or service provider for the correct server names. Otherwise, problems may exist with the newsgroup server.
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. Account information customarily contains user name and password information, as well as host names and port numbers.
If the Mail & Newsgroups set-up screen (Windows and Mac OS only) appears when you try to get mail, you need to set required Mail & Newsgroups preferences.

Your connection may be down. If you cannot establish a connection: ensure that your PPP and TCP/IP software is configured correctly, and that your ISP account is configured for PPP access. Your ISP representative should be able to help you configure your network software.
Before you can display the name of your primary newsgroup server, you must set your Newsgroup Servers preferences. If they are not set, the Mail & Newsgroups set-up window (Windows only), or the Groups Server panel of the Preferences dialog box comes up automatically. Use the Mail & Newsgroups set-up screen or the Newsgroup Servers Preferences panel to set required preferences.
If an invalid newsgroup server name appears for your primary server in the list of servers, provide the correct server name by using the Newsgroup Servers Preferences panel (open the Edit menu and choose Preferences, and then select the Mail & Newsgroups category).
If an invalid newsgroup server name appears for a server that is not your primary server, use the Newsgroup Server Properties dialog box to correct the name of the server.
If you can't access a server using a dial-up connection with autoconnect, check your network software, such as PPP and TCP/IP, and modem settings to see if they're correctly configured to access the server's site. Enable configurations for the server's site, then try opening the server.
