If you continue to receive this message, contact your server administrator or Internet service provider (ISP)."

Re: can't send emails via outlook.

Hello spatterson and welcome,


Please log into your Business Class Portal using the administrator email account. Then under Manage Services click email. View DNS Info. I recommend you print out a hardcopy of your DNS info and keep it handy. Then replace your " " with that which is specified within your DNS Info. I have verified that  your domain email server is hosted by Comcast, that is all you need to do is use the correct smtp.XXX.YYYYYYY.ZZZZZZZ domain outgoing email server address.


Hope this helps you out.

Re: cannot access email via outlook

Outlook Web Access could not find a mailbox for HMC1\ If
the problem continues, contact technical support for your organization and tell
them the following: The mailbox may be stored on a Microsoft Exchange 2000 or
Microsoft Exchange 2003 server, or the Active Directory user account was created
recently and has not yet replicated to the Active Directory site where this
Client Access server is hosted.
