Hi @Skol2you ,
Welcome! There are a couple of ways to go about moving your emails over to Office 365. If you’d prefer Godaddy to handle the migration, please call our sales and support team so they can set that up properly for you. We can check to ensure you’ll be getting the correct box size in GB to fit all your emails. No need to purchase on your own because we will do that together with the migration as a bundle. The other option is more involved and requires your skill and knowledge with creating backups with .pst files using Outlook. I definitely encourage you to contact our team for more information. Have a great weekend!
