## Issue

When using a Microsoft 365 activity with the Application ID and Secret authentication method, you encounter the error: AADSTS70002: InvalidClient - Error validating the credentials. The specified client_secret does not match the expected value for this client. Correct the client_secret and try again.

## Solution

1. In Azure, go to **App registrations**, select your application, then navigate to the **Overview** tab.
2. Check the **Directory ID** (Tenant ID) and **Application ID** (Client ID) to ensure these are the IDs used for your authentication configuration.
3. Navigate to the **Certificates & secrets** tab and generate a new secret to be used in the Scope activity.. This ensures you are using the correct secret. Make sure you copy the **Secret Value**, not the Secret ID.
