    Summary: Outlook PST errors can prevent users from accessing their emails, sending/receiving new emails, or even opening Outlook. The article discusses the potential reasons for errors detected in Outlook PST file and the solutions to troubleshoot and resolve them. It also highlights the importance of using professional tools, like Stellar Repair for Outlook, for resolving complex PST corruption issues or errors.

    Microsoft Outlook is a popular email client to manage personal and professional information. When you configure a POP/POP3 email account in Microsoft Outlook, the client downloads and stores all the mail items, including emails, contacts, calendars, tasks, etc. to a local Personal Storage Table (PST) file by default. Therefore, it’s important to protect the PST file to avoid the loss of mail items due to PST errors or corruption.

    Reasons for Outlook PST Errors

    Before moving to the solutions, it’s important to know the reasons that can lead to errors in PST file.

    • Large or oversized PST file
    • Poor or unstable network
    • Hardware failure or software conflicts
    • Improper or forced system shutdown

    Solutions to Troubleshoot and Resolve Outlook PST Errors

    Below are some solutions you can apply to troubleshoot and resolve the errors detected in the Outlook PST file.

    1. Update Outlook

    Make sure you are running the latest version of the Outlook application. You don’t need to upgrade but must check whether your Outlook client is updated. Updating Outlook can help fix any bugs in the client that may be causing the PST errors. The steps to update Outlook are as follows:

    • Open Outlook.
    • Click File > Office Account and then select Update Options > Update Now.
    Click File > Office Account and then select Update Options > Update Now.
    • Outlook will check for the latest or new updates. If new updates are available, you will see a wizard to download and apply those latest updates to your Outlook.

    Once the updates are downloaded and installed, restart the system and then open Outlook.

    In case you cannot find the option to update Outlook, the setting might be disabled by your administrator. In such a case, update the Windows OS. The steps are as follows:

    • Open Settings on your Windows PC and click Update & Security > Windows Updates.
    Open Settings on your Windows PC and click Update & Security > Windows Updates.
    • Click the Check for Updates button to check if new updates are available or not.
    • If new updates are available, click Install now. This may take a while to complete.
    • After the installation process is finished, launch Outlook.

    This should resolve the issue and errors in the Outlook PST file if caused by a temporary bug in Outlook or Windows OS. 

    2. Reduce PST File Size

    You can also reduce the PST file size if it’s too large. Either you can use Outlook’s import/export feature or archive old mail items to reduce the local PST file size.

    The steps of Import/Export feature are as follows:

    • In Outlook, click File > Open & Export and click Import/Export.
    In Outlook, click File > Open & Export and click Import/Export to start the process.
    • Click Export to a file and click Next.
    • Choose Outlook Data File (.pst) and click Next.
    Choose Outlook Data File .pst and click Next to proceed.
    • Choose the mail folder you want to export and click the Include subfolders checkbox. Then, click Next.
    • Click Browse to choose a location to save this PST file and then click Finish.
    • The Outlook will export all the mail items from the selected mailbox folder or folders to the PST file. Once exported, you can delete the mail folder from Outlook to reduce the original PST file size.
    • Then, open the exported PST file by going to File > Open & Export > Open Outlook Data File and access the mail folder separately.

    Alternatively, you can archive some of the mailbox data to reduce PST file size. Follow these steps:

    • In Outlook, navigate to File > Info > Tools.
    • From the options, choose Clean up old items.
    • Then, choose the mail folder or email account you want to archive.
    • Select the date from the Archive items older than dropdown.
    • Click Browse to choose a location where you would like to save the archived PST file.
    • Once done, click OK.

    Archiving items older than a certain date moves all the emails older than the selected date to a local PST file. As mentioned earlier, you can access your old archived mail items from the archived PST file anytime.

    Note: If you are not able to open Outlook at all due to PST errors, this solution may not apply to you. In such a case, move to the next solution.

    3. Run CHKDSK

    From the Properties window click the "Tools" tab and click "Check".
    • If errors are found or not found, you will see the Scan Drive option. Click on the option to scan the disk for bad sectors and fix them.
    Click on the Scan drive option to scan the disk for bad sectors and fix them.

    Alternatively, you can open the Command Prompt as administrator and then run the below command to scan the hard drive for bad sectors.

    4. Create a New Outlook Profile

    • Close Outlook.
    • Launch Control Panel and navigate to User Accounts > Mail.
    • Click Show Profiles and then click Add.
    • Type any name for this new profile and then click OK.

    • Close all Outlook processes and then press Windows + R to open the Run dialog box.
    • Type outlook.exe /safe and click OK or press the Enter key. This will start Outlook in safe mode.

    • Activate one add-in at a time.
    • Restart Outlook and observe any PST-related error.
    • If no error is displayed, activate another add-in and restart Outlook.
    • Repeat the steps until you find the culprit and then uninstall or remove the add-in from Outlook.

    6. Use Inbox Repair Tool (ScanPST.exe)

    SCANPST or Inbox Repair tool can help fix and repair minor inconsistencies and errors in the Outlook PST file. This tool comes by default with Microsoft Office/Outlook. You can follow these steps to use SCANPST to fix errors detected in Outlook PST.

    SCANPST may fail to repair the PST file if it is:

    1. Larger than 2 GB
