Migrate Service Principals from the retiring Azure AD Graph APIs to Microsoft Graph

So I got this warning/recommendation today in a couple of different tenants. In all cases it points towards "Microsoft Office" using the old API. To the best of my knowledge, this is nothing ive set up but on the other hand, ive only gotten the recommendation in 4 tenants (out of many times that number).

Anyone know what this is about? Feels like if its a feature in Office it should be handled by the company, no?
