What is Office 365 Import Service

To help migration of PST files for users with very large PST Archives, MS just released (currently in Preview) the Office 365 Import Service. Office 365 Import service is the brand new service from Microsoft can use to transfer PST files from your on-premises environment to your Exchange Online mailboxes. You can even ship your files directly to Microsoft Datacenters and MS will upload it to your mailboxes (Isn’t it great?). You have two choices to move your data into Office 365
  • You can ship drives to Microsoft.
  • You can upload files to Office 365.
What you’ll need?
You need to prepare a PST to user mapping file and PST files, and hard drives (if you are shipping to Microsoft). And, permissions and admin roles required for using Microsoft Import Service.
You need to have Mailbox Import Export Admin Role in Exchange online to be able to use this service.
Only 3.5 inch SATA II/III hard drives are supported. Maximum size for each drive supported is 4 TB.
Hard drive should be NTFS formatted and single volume (Microsoft will process only 1st volume discarding all subsequent drive volumes.
Hard drives must be encrypted using BitLocker with encryption keys protected with numerical passwords. The Office 365 drive preparation tool will help with the encryption.
Which Method of Import Service is good for you?
If you have to transfer a large amount of data, and uploading it over the network is prohibitively expensive or not feasible, you can use the “drive shipping” service. In other cases, such as uploading smaller amounts of data, uploading PST files that were missed when you shipped the drive, and so on, you can upload the PST files over the network. Both methods result in the data getting moved into the Office 365 mailbox.
You can determine if your data is small or large based on your network upload performance numbers (bandwidth, latency). Typically, if you have more than 10 TB of data, drive shipping is faster.
