What is a PST File?
When it comes to computing, PST is the term that describes Personal Storage Table. Basically, it is a unique file format that is developed by Microsoft to store important data. For instance, it stores data such as calendar events, messages, notes, and so on.
In some cases, this file format is even known as a “Personal Folder“. This file can even function as the cache for MS Outlook to make its job easier. In that case, it might work as an Offline Storage Table or even as an Offline Folder.
Critical data such as Outlook messages, contacts, calendars, etc., are stored in this folder. This folder can be found on a local computer, so the Outlook application communicates with it when sending emails.
Over time, PST files can start to corrupt or malfunction due to many reasons. One of the main reasons behind a corrupted PST file is too much data. PST files can often get overloaded if you use them for a pretty long time.
As a result, Outlook might not be able to retrieve data from it correctly. That can eventually lead to a 0x800408fc error and prevent you from sending emails through Outlook. So, repairing PST is the ultimate solution to address the 0x800408fc error if none of the other methods work.
In the first couple of solutions, we explain the most basic fixes to the 0x800408fc error. However, if none of those methods work, you should proceed to repair the PST file. But we don’t advise our readers to take a risk by repairing it manually.
This is particularly true if you don’t have prior experience dealing with PST files. In this case, we strongly recommend using a professional Outlook repair tool. We explain it as the ultimate solution to repair MS Outlook applications.
