OST Repair Tool

How To Fix OST File Problems?

OST is an Offline Storage table file created by MS Outlook.  When Outlook is used in conjunction with Microsoft Exchange Server, you can set it to work offline with the Exchange mailbox. OST files store the offline work and as soon as the server is connected and MS Outlook turns online, all the saved emails and information is delivered to respective client immediately. The ability to work offline is useful in environments with limited or unreliable connectivity.

When you work in an Offline mode, MS Outlook creates an exact copy of user mailbox on the Exchange Server, called offline folders, and stores it locally on your desktop. MS outlook names this file as Offline folder file, and stores it with OST file extension.  It is an offline folder file in Microsoft Outlook which makes it possible for the user to work offline and then to synchronize changes with the Exchange server the next time they get connected. OST files are exact replica of the folders of an individual user on Exchange.  Every modification made while working offline, is automatically synchronized when you are connected to Exchange Server.
During the synchronization process, Outlook gets connected to the Exchange server via network, copying all the changes made, so that the offline folders look identical to the mailbox again. You can select to synchronize only a specific folder, a group of folders, or all the folders. A log file will be used to record all the important information about the synchronization, for your reference later.

The OST file contains all your most important personal communication data and information, including emails, folders, posts, appointments, meeting requests, contacts, distribution lists, tasks, task requests, journals, notes, etc. While using Outlook if you come across problem of server breakdown or accidental deletion of email account, then the OST file in use is damaged. It may also happen due to oversized OST file, OST file compaction failure, virus attack on server or on your computer etc. If your OST file gets corrupt or damaged, you will not be able to access your important Outlook data. It leads to very serious problems. OST corruption makes all the data of an Outlook application inaccessible. You cannot even send or receive your e-mails.  

OST file problems are caused due to various reasons:

  • Oversized PST file: Whenever an OST file exceeds the size limit (example: in Outlook 2003, limit is only 2 GB) then there are chances of OST file corruption resulting in errors.
  • Network problem during synchronization: OST file can get corrupted when you experience any network problems or server breakdown during the synchronization of Outlook data file with Exchange Server.
  • Improper Outlook up-gradation: During the importing process of existing Outlook OST file to the new version (outlook 2007, outlook 2010) may also cause incompatibility problems leading to damage of OST file.
  • Accidental system shut down after sudden power failure: If the systems shuts down suddenly while working with .ost file, it results in damage or corruption of OST.
  •  Virus infection: Any sought of virus infection on your OS from the internet, results in damaged OST file.
