How to fix “We Couldn’t Create the Outlook Data File” Issue?

Office Outlook is an email client that allows you to manage users’ email from multiple accounts. Users can add as many emails as they want, but sometimes Office Outlook can’t add the email they want. This is a problem where every time the user tries to add a new email, the error message shows that we were unable to create an Outlook data file. Also, most users reported this error when trying to add Gmail accounts. Other emails such as yahoo, hotmail work well when added.

What is Office Outlook?

Microsoft Outlook is Microsoft’s PIM (Personal Information Manager). It can be used for purposes such as shared mailboxes and calendars, Exchange public folders, SharePoint lists and meeting calendars. Microsoft has also launched applications for most mobile platforms, including iOS and Android. Outlook 2019 has improved performance and reliability with a new multi-threaded model and database improvements. But with all these new features, there will also be bugs. One of these errors is the inability to create the prospect’s database. This error occurs when a user tries to add a new account. There is a bug in Outlook that prevents a user from adding a new account to his database. If you’re dealing with the same problem, this is the right place to solve it.

Why could no errors be generated in the prospect’s database?

Outlook has very good features, but it also has some bugs that can be very annoying. The main causes of this error are as follows.

  • Software error – One of the most common causes of this error is an Outlook error. This error prevents the user from adding accounts to the database. But switching to another way to add an account can solve this problem.
  • Simplified account creation is a new feature of Outlook that has recently been implemented. If you use the simplified account creation function to add an account, you may get this error. Therefore, disabling this function may correct the error.

How do you correct an error in the prospect file?

I will show you here the steps to follow to easily correct the error and add the desired accounts in your Microsoft Outlook.

Note: It would not be possible to add an account in Outlook without the permission of your email service provider. Outlook and other client-side mail must be resolved before accounts can be added. Therefore make sure you have the rights for Outlook on the mailclient side. You can visit the login and security option of Gmail and then select the Passwords application. This gives you a 16-digit code to enter as your password when you add your account.
