App Governance - Inconsistent info

[Dean Gross]

I am getting this alert "An OAuth app with high privilege scopes accessed Teams and made unusual volume of chat message activities through Microsoft Graph API", when I look at this app in Azure AD, there has not been any activity. Can anyone help me resolve this discrepancy?

Hey Dean - i received the exact same alert. Did you find any forensic detail on what this is about?

No, I haven’t found anything helpful

As a follow up, today, I got an alert for "App made unusual email searches activities' and when I look at the Microsoft Graph PowerShell app, it has not been used in over 30 days.
