Restoring a PST File With Outlook 2016 Tools Microsoft Outlook, an absolute leader in the segment of corporate email clients for desktops, stores user data in OST and PST files. An OST file is a cached copy of the user’s mailbox stored at MS Exchange server. A PST file is a personal folders file, containing the user’s email messages and it is stored locally on the computer.
There is quite a number of Outlook users who faced, to a certain extent, problems with opening .pst files because they were damaged. The impossibility to open a user’s archive with email messages results in real headache for administrators and tech support services. In this article, we will focus on the main causes of why .pst personal folder files get damaged and will show you a simple way to restore them. There are various causes of damage to archive files of personal folders in Outlook: damage may result from file system errors (in this case, it is worth starting from checking the file system), and from damaged structure of .pst files caused by an emergency shutdown of the Outlook client (these happen quite often), from a power failure, from virus attacks, from storing .pst files in a shared network folder (Microsoft doesn’t support such configuration) and so on.
