Important: Multi-provider is not supported or is not the same as Exchange hybrid configurations. For strict mode: * Ensure that every strict mode user (in the calendar provider) has a different connection \& credential alias, connection, and credential records. However, you can reuse the same OAuth Entity profile in all the credential records. * While performing the Get OAuth token action for each credential, you must be prompted for credential. When asked, specify the strict mode email credentials. Note: If you are not prompted for the credential, it may use the credential of the logged-in user on the same browser, which is incorrect. You must close the browser and refresh to be prompted about the credentials. {#create-multiple-connection-same-provider__ul_q5v_n15_1yb} Role required: admin ## Procedure 1. For normal mode users 1.
