Therefore, in this article we will discuss the common causes of OST file corruption and the best possible ways to recover an OST file as well as a trick to solve this corruption issue. So let’s we start the discussion.

Brief About OST File

OST files are a user mailbox content replica stored on the Exchange server. It is automatically created on the first use of Microsoft Outlook as soon as you connect to the server. Once created, the data is synchronized with the e-mail server so that it can be used offline as well as in the event of a shutdown of the e-mail server. The user can create email and other data elements in the OST file and, even when you are not connected to the server. But, once you get the connection, the local file is synchronized with the server again and these data items are automatically saved directly to the server.

Upon return of the connection, the OST file is automatically synchronized with the Exchange Server mailbox. It looks comfortable, but in reality, it is not. Like other programs and files, corruption occurs with OST files. Let’s examine the reasons.

What’s the Reason behind OST file corruption?

During the synchronized process, if you’re OST data is disrupted due to bad internet connectivity, then the OST file may be damaged. Once the OST files are disabled, the Outlook functionality will also be affected. In addition to these reasons, there are many other causes of OST file corruption, which is clearly divided into two categories such as hardware and software.

Hardware Related Issues

The corruption issues related to hardware are mainly caused due to inappropriate configuration, malfunctioning, failure in the external components of the computer system such as network connectors, hard drive, modem, internal or external power unit, etc

  • Delay due to network connectors
  • Affected storage device
  • Bad sectors on hard drive
  • Sudden power loss/Surges

Software Reasons

  • Outlook program failure
  • Abnormal Extinction of Outlook
