It allows users to securely access their Exchange Online accounts without having to enter their password each time. Additionally, the protocol helps prevent phishing attacks by ensuring that only authorized users can access their accounts.

How to Setup OAuth 2.0 Client Credentials Flow in Exchange Online
Setting up OAuth 2.0 Client Credentials Flow in Exchange Online is an easy process. First, the user must register the application with the Exchange Online service. This can be done through the Azure Portal. Once the application is registered, the user must create a client ID and a client secret. The client ID and client secret must then be stored securely. Finally, the user must enable OAuth 2.0 Client Credentials Flow in the Exchange Online service.

Conclusion
OAuth 2.0 Client Credentials Flow is a powerful security protocol that helps protect Exchange Online users from malicious actors. It ensures that only authorized users can access their Exchange Online accounts. The protocol also helps prevent phishing attacks by ensuring that only authorized users can access their accounts. Setting up OAuth 2.0 Client Credentials Flow in Exchange Online is an easy process, and it helps ensure that users can securely access their Exchange Online accounts without having to enter their password each time.
