You can access these settings by navigating to 'Settings' in the top right corner of the app toolbar (look for the gear icon) > User.
Record External:
Enable this to record meetings that include external email addresses, such as sales meetings (this can also include colleagues' emails). Typically, you are well set up if you have "Record External" enabled and all other settings disabled, because the bot then joins meetings where you might not be the host.
Record Internal:
This setting records meetings where the calendar invite includes only internal email addresses.
Caution: If you have internal meetings and someone has a different domain, even though they work internally, the bot will not join because that person is seen as external. Please ensure in internal meetings that everyone has the same domain, as this is a critical factor.
