We are making a school dashboard for student to see an overview of what is happening in all the available systems at the school. We want to make Office 365 notifications. We know that this is not a problem with the O365 online API. However, teachers make use of O365 on premise. Is it possible to call an API on this local server and what do the system admins needs to do to make this work? Or, is this in the end, working through he cloud server of O365?
Thanks in advance!
