If you are not seeing email activity log to salesforce it might be due to restrictions on your teams Field Accessibility.
Salesforce's Field Level security gives salesforce admins the ability to put restrictions around what information is viewable and editable by users. When setting field level security you will want to ensure that it is not interfering with the ability for users to see Tout fields.
Work with your Salesforce Admin to ensure that these security settings are not interfering with ToutApp.
If you are a Salesforce admin, you can see your Field Accessibility under the Security Controls tab. The main fields that ToutApp will interact with are: Account, Contacts, Opportunity, Lead, and Task
