Robust Solution to Open Offline Outlook OST File

admin | July 31st, 2015 | Outlook

For every user that is connected to Exchange Server, the basic form of action consists of accessing the mailbox. However, you can also have access to those data in offline server conditions. Microsoft Outlook implements a useful feature for caching of Exchange Server mailbox data on the local hard disk. These files are also known to the users as Offline Storage Table (OST) and are mirror copies of the Exchange Server mailbox.

The main usability of such type of files is that they allow users to work in offline server connections. Later, when the server connections are restored, the data is uploaded back to the mailbox server. However, there are circumstances when these OST files become corrupted and the users are not able to access their important documents. The main difficulty of users starts when they are not able to open the offline Outlook OST files and they look for a robust solution that will help them to do so. Let us understand why such type of circumstances occur and how can we resolve it.

What are the Causes for the OST File corruption?

  • Outrageous Attack: Virus attack that can be too detrimental to make the database corrupted and inaccessible for users
  • Mailbox Deletion: If the mailbox that has been configured to create OST file is deleted by the system administrator accidentally then the OST file becomes orphaned and hence inaccessible.
  • Synchronization Issues: Sometimes there are issues of synchronization between the mailbox and the Outlook. In such a case, OST file becomes corrupted.
