I recently had a requirement to create a dashboard for Exchange in our organisation. When I tried connecting exchange online through PowerBI, I am being connected to my own mailbox. The requirement is to get reports for whole organisation. I got to know that Exchange server doesn't have SQL database or any APIs to get data from.
Requirement could be getting server availability/performance, usage of mailbox, etc.
Thanks and Regards,
The Exchange connector in Power BI only show you a list of items(Mail, Calendar, People, Tasks and Meeting Requests) available in the Exchange account you have entered. It is not possible to use the Exchange connector to analyze the server availability/performance, usage of mailbox, etc.
If you are using exchange online, you can connect to Office 365 adoption content pack , which provides you exchange usage report.
If you are using on-premises exchange, please vote up this idea.
