Ensuring Data Recovery With Outlook 2016 PST File Restoration

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.

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.

You should also remember about the maximal .pst file size restriction in different versions of Outlook. If the maximal file size is exceeded or a large file is opened in an older version of the mail client, Outlook may work with errors. Here are the .pst file size limits:

  • Outlook 2002 and earlier versions – .pst files are in ANSI format and limited to 2 Gb.
  • Outlook 2003 and Outlook 2007 – a limit of 20 Gb.
  • Outlook 2010, Outlook 2013 and Outlook 2016 – .pst/.ost files are in Unicode format and limited to a maximal size of 50 Gb.

Besides, you should bear in mind that the larger the file the higher are the chances of errors, and that is why the recommended .pst file size is 2-8 Gb.

When a .pst file is damaged, the Outlook client can no longer open it, partially or completely, and shows an error message, for example like this:

PST file cannot be found


The file you chose is not an Outlook Data File

Availability of such errors suggests that the .pst data file is damaged and needs recovery of its logical structure.

First of all, let us find out where exactly Outlook stores its .pst files. By default *.pst files (personal folders) and *.ost files (local cached copies of Exchange server folders) are stored in the following directories depending on the version of your operating system:

  • Windows 2000, 2003, XP:
    C:\Documents and Settings\%username%\Local Settings\Application Data\Microsoft\Outlook.
  • Windows Vista, Windows 7, Windows 8 and Windows 10:

However, a user can create/move a personal folders file to another location, if necessary.

Important note! Before you start recovering a .pst file make sure you have backed it up; by doing so you will prevent possible further damage to the file that may be caused by a recovery utility or by Outlook.

To recover Outlook archive folders after being damaged, Microsoft has included a special utility Microsoft Outlook Inbox Repair Tool (scanpst.exe) into the Office package. This small utility is not a cure-all solution to recover a .pst file after any kind of damage but it can help in solving typical issues with personal folders files.

You can find this utility in the directory: C:\Program Files\Microsoft Office\OFFICE {MS Office version number, – 11,12,13,14}.

For example, here is the path to the directory containing the utility scanpst.exe for Office 2016: C:\Program Files\Microsoft Office\OFFICE16.
