Log on Attempts

Steel Contributor

Hi all,

 

I'm trying to figure out the right conditional access policy to block these type of attempts

 

Application: Office 365 Exchange Online

Reason: Invalid username or password or Invalid on-premise username or password.

Client App: Other clients; Older Office clients

Browser: Microsoft Office 16.0

 

I've played around with a few configurations but not sure

Thank you. I have the CA policy to block older clients but this would work for all users and I can use CA for the service accounts we need have basic auth for.
