Hi we use Sage 50 Can edition. just transferred everything to a new desk top. Issue cannot email Invoices from sage I get the following screen: An unknown error occurred connecting to SMTP server. The server may be unavailable or is refusing SMTP connections.  As I am not familiar with SMTP I have searched through Sage Help and found nothing to help, as well as checking through my email but as I am not sure what I am looking for I am not getting anywhere.  Any help would be appreciated. and we use Outlook.com
