We have set up users in our Active Directory that we do not want to set up in Exchange. We want to be able to set up alerts and notifications in SharePoint 2013 to go to the non-company (external) email account of these users. SharePoint is expecting a company email in the profile of these users and is not letting us set up an alert for these users without an internal mailbox. Looking for a way to accomplish that. This assignment is to provide us instructions on how to accomplish being able to set up SharePoint alerts and notifications for Active Directory users to go to an external (non-company) personal email for each one. The instructions need to be detailed enough that our SharePoint admin/sysadmin can follow them, but you won't have to do the actual set up, just provide the instructions.
