Reasons Behind OST Corruption With Appropriate Solution

Offline working mode of Outlook is one of the most outstanding features. In offline working mode Outlook keeps all the user information in .ost file format. Offline working mode is also known as cached working mode of Outlook. With this mode user can even work on Outlook when it is not connected with Exchange Server. User can check old mailbox items such as emails, notes, journals, calendar schedules etc. When the Outlook connects with Exchange all the prior made pending changes go live. Sometimes this OST file gets damaged due to certain reasons. There are several reasons which make OST file inaccessible which are broadly classified into two main categories:

  1. Hardware Reasons
  2. Software Reasons

  • Data storage drive is responsible for keeping all the data but if this disk has some bad sectors then it would not save any data.
  • Though networking is the most essential part of online communication it is important to maintain smoother linking between Server machine and user machine. Any kind of connection error, link breakage and network cable issue can stop communication between Exchange and Outlook which will lead to OST file corruption and create an Orphaned File.
