We have a client running Sage 100 2013 Standard in a peer to peer environment with a Microsoft Small Business Server running Exchange for email. Everything is working well EXCEPT for the email relay. We successfully set up an email account that will send when you logged into the server console. However, when you log into Sage 100 from a workstation, the same configuration will not send email through the Exchange server. I have attached a screen shot of the email server tab in company setup.
