How to find out which clients or users are still using Basic Authentication for EWS, EAS, IMAP, POP and RPS to access Exchange Online?

Is there a report from O365 Admin console?

Thanks, M

We ended up using this Web App which outputs all devices connecting through basic authentication (only free for 10 devices).

Using Azure AD there isn't a direct report but you can get the data you need through the sign-ins log page.

  1. Access the portal.azure.com site
  2. Then Select Azure Active Directory
  3. Then on the left below Monitoring click on "sign-in logs".
  4. Add "Client app" filter and select all entries below "Legacy Authentication Clients".

This will show you all the sign-ins made through basic authenticated devices in the last 30 days.

Article with a step by step on how to find the devices on Basic Authentication quite useful.
