Also, you must know ways to manage an oversized PST file to prevent it from getting damaged or corrupt in the first place.
Ways to Manage Large PST File Manually
You can manage your large-sized PST file manually by following different ways, as mentioned below:
- Split the PST file: To manage large-sized PST file, you can split it into multiple small-sized PST files. However, Outlook does not provide any inbuilt utility or feature to split a large-size PST file. Nonetheless, you can reduce PST file size by using Outlook’s ‘Archive’ or ‘Import/Export’ option. These options do not split the PST file but move mailbox data from one PST file to the other.
- Compact the PST file: In Outlook 2013 and above versions, you can use the ‘Compact Now’ feature to remove deleted data space. This helps compact or compress the large-sized PST file. Outlook automatically compacts its data file, if it contains more than 20% of unused space. You can also manually compact the PST file by following these steps:
- In Outlook, navigate to File > Account Settings > Account Settings.
- In Account Settings window, click the Data Files tab, and then click the .pst file that you want to compact.
- Next, click Settings.
- In Outlook Data File box, click Compact Now, and then hit OK.
- Remove duplicate data from the PST file: Large number of duplicate emails also results in oversized PST file. In that case, removing duplicate emails can help resolve the issue. However, there are various reasons that lead to duplication of emails, including incorrectly configured Rules, short Send/Receive intervals, improper Mailbox settings, incorrect Account setup, third-party anti-virus scanner, etc. And so, you will need to address the actual cause behind the problem to remove duplicate email messages.
What To Do If the Large-sized PST File Gets Corrupt?
You can use Outlook’s inbuilt ‘Inbox Repair Tool’ (Scanpst.exe) to repair your corrupted Outlook PST file. The tool is designed to fix PST file errors.
If the built-in repair utility fails, use a specialized PST file repair tool to repair severely corrupt PST file and recover all the file content.

- Finding different solutions to resolve different Outlook issues requires time and effort.
- Implementing different solutions to deal with an oversized PST file, like splitting, compacting, and removing duplicate data, can be lengthy.
