Hello Wim Huizer, thank you for posting this in the community.

OneDrive syncing and folder redirection are not supported locations for active Outlook data files. Microsoft recommends that PST and OST files are stored only on local, non‑synced disks. When these files are stored in OneDrive, Outlook may lose access to them.

This error occurs because Outlook is still trying to access the data file using its old OneDrive path. After the file was moved to the laptop’s local drive, Outlook was not updated with the new location, so it can no longer open the file.

This is not a case of corruption or data loss. Your email data is still safe, and the issue is simply an incorrect file path. It is a configuration problem, not a mailbox failure.

To resolve this, first ensure that Outlook and OneDrive are fully closed. Close Outlook completely and exit OneDrive by right‑clicking the OneDrive icon in the system tray and selecting Quit. Verify in Task Manager that outlook.exe is no longer running.

After that, create a new Outlook profile so Outlook can rebuild its configuration and correctly reference the local data file location. See this article, Create an Outlook profile

Kind regards,

John Oli

    The error 0x8004010F typically occurs when Outlook cannot access the data file, often due to a corrupted profile or incorrect file location. Since you mentioned moving the Outlook data files from OneDrive to your laptop drive, you may need to update your Outlook profile to point to the new location of the data files. Here’s how you can resolve this issue:

    1. Locate the Default Outlook Data File:
      • Open Control Panel and select Mail.
      • In the Mail Setup - Outlook dialog box, click on Show Profiles.
      • Select your current profile and click on Properties.
      • Click on Data Files to see the current location of your default data file.
    2. Create a New Outlook Profile:
      • In the Mail Setup - Outlook dialog box, click on Show Profiles again.
      • Click on Add to create a new profile and follow the prompts to set up your email account.
      • Make sure to select Manually configure server settings or additional server types if necessary.
      • When prompted, browse to the new location of your Outlook data file that you moved to your laptop.
    3. Set the New Profile as Default:
      • In the Mail dialog box, select the new profile you created and set it as the default profile.
    4. Restart Outlook:
      • Close and reopen Outlook to see if the issue is resolved.

    If you still encounter issues, consider checking the integrity of the data file or creating a new data file altogether.
