Hi, We have thoroughly reviewed your listed issue and identified the root cause. It appears that an incorrect value was entered for the client ID. Please ensure the configuration accuracy as follows: For the client secret in CRM, enter the values highlighted in the screenshot. For the client ID in CRM, input the Application (client) ID value as highlighted in the screenshot. [ans 1] [ans 2] [ans 3]

For outbound you have to create an “app password” for each user and use that as outbound connection. Your Azure login/password will not work. There is also a setting in Azure to allow this or not. If this is not allowed, even creating an app password will connect for outbound.
