For starters, I am assuming you have a valid Office 365 account, a SCOM environment (with Internet access), and the Office 365 Management Pack.
Once you have imported the MP, next within the Administrations tab, you will need to add your O365 subscription. I used the “All Management Servers Resource Pool” for my Server Pool.
Once successful, you should have your Office 365 Subscription within the Office 365 Overview:
If you go back to the Monitoring tab, you should now see the Office 365 folder along with some native views.
I went a step further and added the, “Message Center” webpage, same view you would see within an browser.
I copied the two views from the MP into My Workspace, and added a new Web Page view, with the URL here, https://portal.office.com/MessageCenter/MessageCenter.aspx.
When you launch the view the first time, you will be required to sign-in. I also check marked “stay logged in” to avoid this down the road.
And that is it! Pretty easy!
