Planner group email address blocks external emails

Occasional Visitor

I have an employee who has been using the Office 365 web portal to access his email. He only relies on the autocomplete feature to track his contacts.  Is there a way to export the autocomplete files from the webportal and import them either into Outlook itself or into his Contacts?
