I have just recently upgraded to Exchange 2007 (single server enviorment, no edge server) and we are now having some issues with our photocopiers sending network scanned documents to users outside of our internal domain.
With Exchange 2003 the copiers were setup with SMTP authentication using an AD account that was created specifically for them. Now we have upgraded the copiers and no longer able to authenticate correctly using their credentials, I just get the error "authentication failed, check your username and password". If I uncheck SMTP authentication I am able to send scanned documents from the copier to internal users but not to external users.
I assume that this has something to do with the recieve connector but I cannot find the correct settings, any ideas?
