Oftentimes when your Outlook mailbox becomes full, exporting your old emails to a PST file for safekeeping is a great way to free up space. But, this convenience quickly comes into question if you’ve accidentally deleted the PST file and all its contents with it.

What Is a PST File?

The PST file extension is a Microsoft Outlook Data File. When you connect an email account to Outlook, a PST file is created locally. It contains information relating to your linked Outlook account, such as email messages, calendar events, and information for your contacts. PST files are used by POP accounts, as well as IMAP accounts in Outlook 2013 and earlier versions. They can be useful if you ever need to recover deleted Outlook emails as they also act as a backup.

Where Are Outlook PST Files Saved?

If your PST file was created using Outlook 2013 or later, it would usually be saved in the Outlook Files folder located in your Documents folder. However, if the PST file was created with Microsoft Office Outlook 2007 or earlier, it will be saved in a hidden folder at the location <DRIVE:>\Users\<USER>\AppData\Local\Microsoft\Outlook.

How to Recover Permanently Deleted PST Files

When you recover a deleted PST file, any information inside it will also be recovered, such as stored emails. For this reason, using an effective PST recovery tool can often save you a lot of time and hassle. Disk Drill for Windows is a data recovery tool that specializes in the recovery of such files. It’s trusted by many for its long track record of successful recoveries.

Follow these steps to recover a permanently deleted PST file:

  1. Download and install Disk Drill. Avoid installing it on the same drive where your PST file was located.
  2. Select the drive that contained the PST file and click Search for lost data.Scanning the drive with Disk Drill.
  3. Click Review found items once Disk Drill’s scan is finished.Reviewing the discovered items.
  4. Navigate to where the PST file was stored. Alternatively, use the search bar in the application to find any files with the PST extension. Mark the file, then click Recover.Recovering the PST file.
  5. Select an output location. Again, avoid choosing a location on the same drive you’re recovering the PST file. To recover the deleted PST file, click OK.Confirm Disk Drill recovery.

Disk Drill is designed with ease of use in mind, which is why it’s just as easy to recover deleted desktop files as it is your Outlook PST file. Once the file is recovered, be sure to create a copy of it to avoid losing it again.

How to Recover Deleted PST Files Without Software

If you don’t want to take the data recovery software route, you still have a few options available to perform Outlook PST recovery.

Method 1. Check the Recycle Bin

One of the easiest free ways to restore deleted PST files without software is Recycle Bin recovery. Your Windows Recycle Bin captures deleted files and temporarily holds them in case you want to restore them after they were accidentally deleted.

Here’s how you can recover a PST file from the Recycle Bin:

  1. Open the Recycle Bin on your Desktop.Opening the Recycle Bin.
  2. Right-click the PST file and click Restore. Alternatively, simply drag it out of the Recycle Bin.Restoring the PST file.

The Recycle Bin is a great way to recover folders and files in Windows. However, if the bin was already emptied, you can use the next step to recover PST files deleted from Recycle Bin.

Method 2. Using Restore Previous Version Feature

The File History backup tool may have a snapshot containing a previous version of your PST file. When configured, File History automatically takes periodic snapshots of specific files and folders, allowing you to recover deleted files in Windows 10 and 11 without the need for third-party software. Furthermore, since it takes multiple snapshots of the same file at different points in time, you can restore previous versions. Of course, the key requirement here is that File History needed to be enabled prior to the deletion of the file.

These steps will guide you through recovering a lost Microsoft Outlook PST file with File History:

  1. Navigate to the folder that once held your PST file. Click Home, then History.Opening File History.
  2. Select the PST file and click the green restore button.Restoring the PST file from File History.

Should the file not be available through File History, you can also check the other backup utility included with Windows, Backup and Restore.

Method 3. Recover From Backups

The AutoArchive feature is available in Outlook versions 2003 and later. When enabled, it automatically moves Outlook items of a specified age to an archive folder, freeing up space without permanently deleting them. If the items you need were set for automatic archiving, you can find them in this backup.

This is how you can open an AutoArchive backup in Outlook:

  1. Click File.Accessing the Outlook File settings.
  2. Click Open & Export.Accessing the Open & Export section.
  3. Click Open Outlook Data File and select the archive. Unless it was changed manually, the default location is Documents\Outlook Files.Opening the PST archive file.
  4. Explore the archive using the new Archives dropdown that appears below your mailbox.Checking the archived data.

Alternatively, you can explore other local backups that may contain the PST file. In addition to File History, Windows also includes Backup and Restore, an older backup feature. If it was configured prior to the deletion of your file, it may be held here.

Conclusion

Deleted PST files can easily be recovered on Windows 10 and Windows 11, even when they’re seemingly gone for good.

If neither of these options is viable for you, use a data recovery tool to take care of the job for you.
