Setup email on a new machine tends to pose the question of how to transfer an OST file to a new machine. This is a common situation when upgrading your laptop, job change, or gain access to archived emails on another device.

Nevertheless, moving OST files is not an easy task since they are limited to particular Outlook profiles and accounts. Here’s a step-by-step guide to transfer OST to new computer with all information attached.

An OST file, or Offline Storage Table, is a Microsoft Outlook data file used to save a local copy of your mailbox information from accounts such as Exchange, Office 365, or Outlook.com. It enables you to view emails, calendar appointments, contacts, and tasks even when you are offline. Any offline modifications you make are automatically synced with the mail server when you come back online.
