  • Network Upload: You can the temporary Azure storage location for uploading PST file over the network. Then use the Office 365 Import service to directly import PST files to Office 365 account (free of charge).
  • Drive Shipping: Using the Office 365 import service is quite a difficult task, therefore, Microsoft handles the import task for you and charges USD 2 per GB of data. You just need to copy your PST files to a Bit-Locker encrypted external hard drive and then ship it to the Microsoft data center.
