I have migrated my users to Exchange Online Office 365. I have placed in several new Savin 4305 copiers. Before the migration I had an Exchange 2013 server on premise that relayed the smtp for the copiers. Now that I have migrated I have lost the ability to use the Exchange 2013 server since It has been removed from my network. I need to know what method and how to setup that method to provide the ability to my users again using the Savin copiers to scan to email and also receive the donotreply@ emails sent from the copier.
