I have an issue where I need to check a Microsoft 365's email for the exact email they put into the To field, and if the sender is internal to my organization. I've found the only trigger for MS 365 groups are only seem to specify which group's email we're targeting named "When a new email arrives to a group" of the Office 365 Groups Mail category.
After this trigger, I need to have an email sent in response with a message, but I don't think that should be difficult to create.
