Microsoft Outlook is a widely popular email client which is used by several companies and their executives. It allows users to add multiple email accounts, including Gmail, Yahoo, Exchange, Office 365, etc., and work on them simultaneously. Instead of accessing each of them on different platforms, a unified interface makes managing email messages much simpler.

The process of configuring an email account in Outlook is easy. However, some users still experience an error- ‘We couldn’t create the Outlook data file,’ especially with Gmail accounts. This error does not allow them to add the account in Outlook. This is clearly a problematic situation that needs to be resolved at the earliest.

Reasons behind the ‘We couldn’t create the Outlook data file’ error

This is becoming a well-known error, and to avoid it from occurring, you must be aware of all the reasons which cause it-

  • Bugs in Outlook
    Bugs exist even in Outlook. These bugs prevent the users from adding a new account through the File> Add Account approach.
  • The Simplified Account Creature feature
    Simplified Account Creation is a relatively new feature that was introduced with the aim of making things easier. However, even this contains many bugs and becomes one of the main culprits for this error.
  • Lack of space on the hard disk
    To add a new account, some amount of free storage is needed on the hard disk. A storage media overfilled with files is not recommended.
  • Email client permissions
    Certain security permissions of email clients often come in the way of using them on a different platform. Ensure that all settings are properly set.
  • IMAP and two-step verification are disabled
    If you are trying to add a Gmail account to Outlook, the IMAP and two-step verification settings must be enabled properly.
Methods to resolve the ‘We couldn’t create the Outlook data file’ issue

Outlook is throwing this error either due to an underlying problem with itself or with the email account which is being added to the platform. The following methods focus on resolving both the aspects of the error-

  1. Free up disk space

    Any email account which is being added requires sufficient free space in the hard disk of the system. You can quickly check if it has space or not-

    • Open This PC which will mostly be present on the desktop itself.Open This PC
    • Under Devices and drives, you can check the remaining space in the hard drives.check the remaining space in the hard drives

    However, if it is full, you must delete the applications which are no longer used and run a quick scan through the Disk Cleanup tool. In addition, consider clearing the Outlook cache and Windows cache data.

  2. Remove Write Protection from the hard disk

    The Write Protection forces a storage medium to be in the Read-only zone. When this is enabled, the disk cannot apply modifications and other amendments. If that is the case here, it must be removed from the hard disk.

    • Open the Run window (press the Windows and R keys together).
    • Type diskpart and press OK
    • Now, type the commands below and click Enter after each of them:
    • List disk
      Select disk (number)
      Attributes disk clear read- only
    • Disable the Read-only protection. Type the exit command and press Enter.
  3. Disable Simplified Account Creation facility

    If you are using the ‘Connect Outlook to Office 365’ wizard to add your email account to Outlook, this error is bound to occur. This Simplified Account Creation facility has to be disabled to prevent this.

    • Open the Run window (Windows + R).
    • Type regedit and click on OK. The command will open the Registry on OK
    • Now, you can go to the following address path-
    • HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\setup
    • Right-click and select New. Click on DWORD (32-bit) New
    • Change the name of the file to DisableOffice365SimplifiedAccountCreation. Enter 1 as the Value data and press on on OK
    • Close this window and restart Outlook.
  4. Check account settings

    There is a possibility that the problem lies with the email account which you are trying to add and not Outlook. The email client is not allowing complete access to the user. Also, make sure you are entering the correct email address and password. And if you are trying to add your Gmail account, then also check for the following-

    • IMAP setting is enabled
    • Two-Step verification is successfully completed
  5. Add a new account in Outlook

    If the above-mentioned methods have not helped you to resolve the Outlook data file error, you can try these other approaches to add your account to MS Outlook.
