Hi Qwerty13,
According to your description, I understand that you want to move users and emails from Google App to Office 365.
If this is the case, I suggest you refer to the following steps:
1. Choose your domain and set up user accounts.
2. Set up email.
In addition, if you are using Outlook, you can use the .PST file to transport the email from one account to another, for the detailed steps, please refer to Use Outlook to Move Data Between Accounts.
Thanks,
Eben Liu
