Outlook provides some really great features that make your email easier and faster. However, many users face various problems while using Outlook. One of these problems is Outlook cannot access your personal data file.
The exact error message should look something like this:

When this error occurs, you cannot send or receive emails and Outlook keeps showing the above error on your screen. This error is usually the result of a corrupted Outlook profile. There are several ways to fix this problem and make Outlook recognize data files.

The easiest way to fix the “Can’t find Outlook data file” error is to create a new profile and use it as your primary profile in Outlook. This will get rid of the configuration issues of the old profile and allow you to start over.
