According to published documentation:
https://learn.microsoft.com/en-us/exchange/clients-and-mobile-in-exchange-online/deprecation-of-basic-authentication-exchange-online
We should use the Azure Active Directory Sign-in report to determine who is still using Basic Authentication
The link provided in the above document is this:
https://techcommunity.microsoft.com/t5/microsoft-entra-azure-ad-blog/new-tools-to-block-legacy-authentication-in-your-organization/ba-p/1225302
Following that procedure, in addition to the Exchange Online protocols, we also get entries that read "Reporting Web Services" and "Other clients"
This article provides guidance for "Reporting Web Services" using Basic Auth.
Is there any guidance on entries that are listed as "Other Clients" and when they may be affected.
I have two critical service accounts that may be affected.
