Free Methods to Export OST Files:Step-by-Step Guide and Practical Scenarios

2 Free Methods to Export Outlook OST to PST Manually

Microsoft Outlook is one of the most advanced email clients supporting multiple features. MS Outlook saves the data in OST and PST file formats. An OST file also known as Offline Storage Table allows users to work offline.

I've found that many users get confused between OST and PST files - think of OST as your "working copy" that syncs back to the server,while PST is more like a standalone backup file you can move around freely.

Here are some scenarios when exporting an OST file to PST becomes very helpful:

  • A few Exchange mailboxes get deleted from the server
  • Looking to create a backup of Exchange mailboxes
  • When an Exchange user needs to rebuild their OST file but has unsaved offline data,but the user has some unsaved data in the OST file
  • When OST files become oversized,conversion from OST file to PST can save the data from corruption

Users have several options to convert OST data to PST. They can log in to Outlook with the same Exchange profile. Some native methods are helpful to export from one file format to the other.

  • Export mailbox data to PST
  • Archive OST emails
  • Convert OST mailbox to PST Using an Automated method.

Method 1:Use Outlook Import and Export Wizard

Login to Outlook account that users have used to create OST files. Now,follow a few steps to convert the selective OST files to PST. These steps are simple to follow.

  • Take your mouse to Files>Open &Export and from there click on Import &Export.

Note:The manual method allows users to lock the new PST file. They can either lock the file or keep it unlocked. It is an optional feature.
Quick tip:If you're dealing with a large mailbox,the export might take a while - I usually grab a coffee while it processes!

Method 2:Auto-Archive OST Mailbox Items to PST

It is another popular method to save OST files to PST. With the activation of the Auto Archive method in Outlook,users can save items of an OST file in a separate PST file. The method is effective to manage the size of your mailbox. As an OST file gets old,the file size increases. It holds a number of messages that you may not need in the mailbox. You can keep these files in the archive folder. Follow the manual method for auto archiving in Outlook.

  • Access your Outlook application,go to File,and press the Options tab.
  • From the drop-down,take your cursor to the "Advanced" tab and then press Auto Archive Settings.
    Auto Archive Settings
    Navigate to Auto-Archive Settings in Outlook
  • A new window will pop up. It is the Auto Archive wizard. Now choose the number of days you wish to run auto-archiving. Select the folder to save the archived file;don't forget to provide the archiving options and in the end press OK .
    Auto Archive Options
    Configure Auto-Archive scheduling and storage paths

Now,the mailbox items of your OST file will save in the PST file format as per your archiving settings.

One thing I've noticed - archiving works great for cleaning up your main mailbox,but remember to check your archive folder occasionally so you don't lose track of important emails.
