You probably receive lots of circulated emails to pass forward; some are worth reading, but many are not. 
 
If you do decide to forward them, for the sake of confidentiality, ALWAYS remove any ‘from’ addresses and even ‘to’ addresses and then send to your recipients ‘blind’ (bcc).

No names or email addresses will show up when your message is opened.   This is great to use when you are sending to a large number of people and do not want them to have to scroll through a page of names before getting to the content of the message.

You can also send emails ‘bcc’ when you want to send a message to someone, and copy another person, but you don’t want the main recipient to see the ‘copied’ person’s name.  If the person replies to all, the ‘bcc’ recipient does NOT get an email.

To add the bcc line to all of your outbound emails 
• Open a new email message, look along the top of your toolbar click on the ‘Options’ tab.
• Look along the bottom of the toolbar for the column called ‘Fields’.
• Click on ‘Show Bcc’.

To remove all previous recipients from a forwarded email
• Open the email.
• Click on the Message tab up on your email toolbar.
• Click on the ‘Forward’ command.
• Left click your mouse on one name or email address to highlight it.
• Right click on the highlighted email and choose ‘select all’ from the popup menu.
• Delete all highlighted names to clear the line.

To add bcc email addresses on your own forwarded emails
• In the ‘bcc’ line of your new email, add the addresses of those to whom you want to send the email.

You will see the names before you send the email, but your recipients will not see the name of the person receiving BCC messages.
