Hi, I am trying to register a host to mailhost. I am using Outlook 2002. I have successfully registered an Internet ISP by copying and pasting the View -> Options -> Internet Headers section into the top and the body of the email into the bottom of MailHost Return. When I try to register the account from the Exchange server, using the above method, I get the "Headers not found." error. I know there are copious amounts of Outlook/Exchange Header not found posts - but I could not find a solution other than what I have performed above, which is not working in my case. I have tried forwarding the email as an attachment, and also a new mail with the headers obtained from View->Options->Internet headers and the body. They all return "Headers not found.". Any ideas?
