  • Data transfer: All data stored on the server would be migrated to However, drafts and outboxes would probably get deleted since they are stored on the system locally. You could back them up if needed.
  • Auto-complete addresses: Anything that happens to these lists would be similar to the action upon re-building a new Outlook profile. In usual cases, would pick up email addresses from the list of ID’s you have mailed to.

No product is perfect, but Microsoft is trying to make this transition as smooth as possible for users.
