Are you bothered by “We couldn’t create the Outlook data file” error? Take it easy. MiniTool Solution gives you 3 methods in this post. You can fix this error by yourself with the given instructions.

As one of the most popular email clients, Microsoft Outlook can help users manage emails from multiple account. However, while adding various different emails to Outlook, you may fail to add a new email and receive the error “We couldn’t create the Outlook data file”.

It’s worth mentioning that this issue appears only when adding the Gmail account. Microsoft Outlook works well if you add other email providers.

Reasons for This Error

You may wonder why Outlook couldn’t create data file. There are two main reasons for this error.

  • Outlook bug: This is the most common cause of this error. This bug in Microsoft Outlook prevents users from adding accounts from the option of Add Account. In this case, you can switch to another method of adding account.
  • Simplified Account Creation feature: As a newly added feature, it comes up on the start of Microsoft Outlook. However, the mentioned problem might appear if you use this feature. Sure, you can fix the issue simply by disabling it.
Note: If you don’t get proper permissions from your email provider side, you cannot add email account to your Outlook as well. Thus, please make sure that you have allowed Outlook from your Gmail.
