Microsoft Outlook is probably the number one choice for businesses around the world due to all the right reasons. This application comes with advanced features and has a stable software program that often does not crash, making it the preferred choice for personal and organizational use. Just like any other application, MS Outlook has a few issues that, when they occur, can affect the user’s workflow.

The outlook.pst cannot be found error is an error message that can occur when using your Outlook account. The PST file, otherwise known as the Personal Storage table, is a data file with copies of your messages, events, and more.

However, this error occurs when the software is unable to locate a PST file on the system. In this article below, I have mentioned why this issue occurs and the different ways of fixing it. If you want to learn about them, be sure to check out this article until the end.
