Identify all users using Basic Authentication

[steve_elliott]

Is it possible to run a PS script of some sort which would identify all users who are connecting to O365 services (Exchange) using basic auth.

When we run the report via the GUI in Azure AD Sign-In's blade and filter by 'Client App' - this gives u the info we need but the export is limited to 5000 events.

Is there a way to extract this info to a CSV via powershell?

We've designed a tool which sends you an excel with all devices still using Basic Authentication and how to migrate them to Modern Authentication, might be helpful.

We implemented it exactly due to the Azure AD export limitations.

Let me know if you find any issues.
