Moving Messages from Office 365 to Gmail

When you opt into Gmail, the mail you have previously received and the calendar entries and contacts you have previously entered in your Microsoft Office 365 (O365) account will not be automatically transferred to your USC Gmail account. This document provides instructions on how to automatically transfer your O365 data to Gmail using the Gmail migration tool and how to manually transfer your O365 email using Outlook 2016 for Mac.

NOTE: When you opt into Gmail, you will still be able to access all of your previous Office 365 emails, contacts, and calendar data by logging into the Outlook Web App (OWA).
