Office365 is a cloud-based solution which allows you to host email and SharePoint at microsoft’s servers on the cloud. And if you already use this solution and starting using the SCSM when early or later you want to send notifications to Exchange Online mailboxes.

In this post I’ll talk how to setup and configure all chain to send notifications from SCSM to Office365.
