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-

  • 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.

Method 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.

Method 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.

Method 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
