A corrupt PST file may cause you a lot of distress, but that's not entirely necessary. These files are repairable and there are plenty of solutions to try. Read this article and find out the best tools to use to repair PST file Outlook 2016.

1Reasons that May Cause Issues on PST

Let's start by looking at some of the reasons for PST corruption, damage, or problems with the file in general.

  • Large File Size. Over time, as you save more emails and Outlook continues downloading those emails for offline access, the PST file size increases. Eventually the file may be too large and as a result, could corrupt.

  • Importing Error. Did you recently import the PST file on Outlook? Perhaps Outlook wasn't able to access the PST properly due to permission errors or system errors.

  • Computer Virus/Malware. Viruses can be designed to target email account information so that hackers can gain access to your information. Opening an email that contains a virus could infect the PST file, rendering it inaccessible.

Understanding the causes of a problem like this can help you take steps to avoid PST corruption in the future. Sometimes it isn't avoidable though, and you'll need to repair Outlook PST file.
