We are starting to plan a MIM 2016 development. The scenario consists of on premises AD and MIM server(s) with Azure AD Connect installed on its own server. There is the cloud and Azure AD plus Exchange Online.
There is NO Exchange 20xx anywhere, all mailboxes now live in Exchange Online.
We are asked to create new on-prem AD accounts via MIM from an HR feed. AADC will sync these to Azure AD. MIM is also tasked to make Exchange Online mailboxes & license the things via a Powershell script when the account is in Azure.
All ok so far.. except that the Managers and Service Desk want Notifications to be sent BY *MIM* when a new AD account is created and again when a (licensed) mailbox is successfully created.
How is MIM and the myDomain\MIMService account configured to send Email notifications without an on-prem Exchange?
I am guessing/hoping that Exchange Online can act as a SMTP server... but really how is it done?
