  • Network Device Failure: Suppose, your PST file is saved on a Network Server and you are trying to access it from client computer through network links. If the network links like routers, cables, hubs, routers, network interface cards, etc have some problems, then PST file may get corrupt when you try to access it.

Software Reasons: Some software reasons, which cause PST file corruption are:
