Solutions to Resolve This Data File has not been Configured Error

Follow the below-given solutions in the given order to resolve the error and restore access to the Outlook data file (PST).

1. Verify the PST File Path

You may usually encounter this error if Outlook fails to locate the data file at the default location. This might happen if you have moved your data file to another folder or directory path. So, verify that the Outlook PST data file is located in the default folder directory. The steps are as follows:

• Open Outlook and go to File > Info > Account Settings > Account Settings.
• Under the Data Files tab, choose the PST file that belongs to your account and click Open File Location. This opens the default location where PST file is stored.
• If you see the PST file here, the path referenced is correct and there could be some other issue.

However, if you can’t see the PST file here, you need to add the PST file from the new location. For this,

• Under the Data Files tab, click on Add and browse to the new location of the PST file to add it.
• Once added, restart Outlook. The error should be resolved.

2. Check and Update Outlook

You can update the Outlook client to the latest version. Updating the application will help get rid of any bugs or incompatibility issues that may have triggered the error. Follow these steps:

• In Outlook, go to File > Office Account > Update Options.
• From the dropdown options, choose Update Now.
• A update wizard will start. Complete the wizard to install the updates and then restart the system.

• Launch Outlook and see if the error is resolved.

3. Disable Problematic Add-Ins

Faulty or incompatible third-party add-ins can cause errors and performance issues in Outlook. Follow these steps to find and remove the faulty add-ins:

• Open Outlook in Safe Mode. For this, hold the Ctrl key and double-click on Outlook application icon or type outlook.exe /safe in the Run dialog box.

• If you do not see the “This data file has not been configured” error in Safe Mode, it means add-ins are the reason behind the error.
• Go to File > Options > Add-Ins.
• Beside Manage COM Add-ins, click Go.

• Uncheck all add-ins and restart Outlook normally.
• Now enable the add-ins. You need to enable them one-by-one. This will help identify the problematic add-in. Once found, immediately remove it to resolve the issue.

4. Create a New Outlook Profile

Corrupt or damaged Outlook profile can also cause the “This data file has not been configured” error. In this case, you can create a new Outlook profile. The steps are as follows:

• Open Control Panel.
• Go to User Accounts > Mail > Show Profiles.

• Click the Add button.
• Type a name for the new profile and click OK.

• Type the credentials to setup your email account under this new profile.
• Once configured, remove the old profile and launch Outlook. You may also keep the old one and make the new one default.

5. Repair or Reinstall Outlook

Corrupt or damaged Outlook program files, such as the driver files or DLL library files may cause interference and performance issues in Outlook leading to such errors. To resolve this, you can try repairing the MS Outlook installation by following these steps:

• Open Control Panel.
• Click Programs > Programs and Features.
• From the listed programs, choose Outlook or Microsoft Office.
• Then, click on the ‘Change’ button at the top.

• From the available options, choose ‘Repair’ and then click ‘Continue’.

• This will start the repair process. After the repair is done, restart Outlook. Check if the error is resolved or not.

If repairing MS Office or Outlook did not work, you can go ahead and reinstall Outlook. However, you must make sure that you have back up of your PST file before proceeding.
