Ok, I think I may have answered my question - I can open the message and then click on the Message Options button (the little square at the lower right of the 'Options' section of the ribbon in the message window). Even more infuritating - if I do a Reply All in Outlook, the email addresses show, but if I copy + paste then again only the names show up!! To field - but I can't do that since the Outlook forwarding has removed the email addresses.
So I forward that email to my other account, and then I want to reply to it and add all the email addresses into the The reason this is a problem is I want to forward this email to another email account of mine, and then send a response from there. Is there no option to get the email addresses to show? I can display the email address one-by-one by double-clicking on a name, I forward that message in Outlook (or print preview), only the names show for the To field, not the email addresses. These are all 'external' addresses I assume, as we are not using Exchange server and the sender is probably not even using Outlook. Someone sent an email to a bunch of people.
I believe I'm having a similar problem using Outlook 2007.
