Summary: Outlook users need to backup OST file to protect their data or migrate mailbox to another system. In this post, we have provided different methods with stepwise instructions to backup Outlook OST file.

In Microsoft Outlook, the mailbox data is saved in two types of files – OST and PST. If you have an IMAP or MAPI email account, then Outlook creates an Offline Outlook Data File, which is commonly known as the OST file. In case you have a POP3 email account, then Outlook creates a Personal Storage Table (PST) file.

OST file is an offline cache of your server mailbox that is saved locally. So, if you delete this file, you can recreate it by downloading the mailbox data from the server.

Why do You need to Backup Outlook OST File?

Some common reasons why you need to back up your Outlook Storage Table (OST) files are:

  1. Data Safety: If your OST file becomes orphaned, then you can’t read your emails and access other important mailbox items. This is because you don’t have access to your Exchange Server mailbox. However, if you have a backup of the OST mailbox, then you can restore the OST data from the backup.
  2. Recovering Lost Data: If you accidentally delete some important emails, contacts, etc. from your OST file, then the same will also be deleted from the Exchange Server. However, if you have a backup, you can use it to restore the deleted mailbox items.
  3. Mailbox Migration: If you have converted your OST to PST as backup, then you can easily migrate your Outlook mailbox to another system or a new Outlook profile. This is because you can directly import PST into any Outlook profile.
