Summary: There are some situations where you may need to import OST to Outlook, and if you are facing this issue, this guide will help you. Here, we will discuss three effective and tested methods to transfer OST files into Outlook. So, keep reading to explore both manual and professional solutions to fix your problem.

Why Can’t You Directly Import OST to Outlook?

OST (Offline Storage Table) files are used by Outlook to store mailbox data when working offline. However, Outlook does not provide a direct option to import OST files. If you try to access OST file directly, you will encounter errors because Outlook only supports importing PST (Personal Storage Table) and MSG (Outlook Message) files.

Why Do Users Need to Transfer OST File to Outlook?

  • Switching to a New Outlook Profile: If your old Outlook profile becomes inaccessible or you need to set up a new one, you might need to import OST files to Outlook to access old emails and data.
  • Recovering Data from Orphaned OST Files: Sometimes, OST files become orphaned due to account deletion, Exchange server crashes, or accidental deletion of the original profile. In such cases, users need to import OST to Outlook to regain access to emails.
  • Migrating from Exchange Server: Organizations often migrate from one Exchange Server to another or move to a different email environment. During such migrations, users require a way to import their OST files into Outlook.
  • Backup and Archiving Purposes: Many users prefer to back up their Outlook mailbox by converting OST files into a format that Outlook can open, such as PST, to ensure long-term data storage and easy retrieval.

How to Move OST File to Outlook Mail?

If your Outlook profile is active, you can transfer OST data via an IMAP-configured email account:

  1. Create a new IMAP account (such as Gmail or Yahoo) and configure it in Outlook.
  2. Drag and drop your OST emails into the IMAP folder in Outlook.
  3. Allow Outlook to sync emails with the IMAP server.
  4. Configure the same IMAP account in another Outlook profile and sync the emails.

Drawbacks of Manual Methods

The first method requires access to the Outlook profile linked with the OST file. If the account is inaccessible, this method won’t work.

The IMAP method requires manual syncing and does not retain all Outlook elements like contacts, calendar, and attachments.
