Relevant for ALL integration mapping, we have use cases where Salesforce (or the integration) uses usernames that have one domain, while the calendar account uses a different domain.

At present, if someone joins with their calendar, it cannot do automatic mapping for integrations due to the difference in domain names.

It would be great to support a global domain mapping in the integration screens so that domain.com -> email.com always, therefore if we find user@domain.com it will know to map it to user@email.com.
