Want to access your orphaned OST files? Convert OST to PST

When you try to access Exchange server 2000 or 2003 mailbox through MS Outlook e-mail client application, you fail to log on to Exchange server database and one of the following error messages appears on your screen:

Unable to display the folder. Microsoft Office Outlook could not access the specified folder location. The operation failed.

The above mentioned error occurs in the Active Directory directory service when the Create named properties in the Information Store permission is not assigned to the Everyone group to the CN=Configuration, DC=Domain, DC=com, CN=Services, CN=Microsoft Exchange, CN=Organization object. A second possibility could be the corruption in .ost file or Outlook has some synchronization problem with Microsoft Exchange Server.

First, let us go back and find out more about Exchange Servers and OST files.

In a corporate environment, MS Exchange Servers are deployed as an efficacious means to manage business communication through emails. In the absence of Exchange Servers, MS Outlook users work on their mailboxes using OST files. The .ost files are exact replicas of their Exchange Server mailboxes. Whenever, the connection to the MS Exchange Server is re-established, the OST files synchronize with the user mailboxes on the server and all the changes are reflected in the current mailboxes.

But what happens when the same OST file fails to synchronize with the Exchange Server? The user mailbox data and all the changes made to it are rendered inaccessible for future use. When the user mailbox becomes permanently unavailable, the OST file becomes orphaned.

Causes of OST file corruption

OST files become orphaned/corrupt pertaining to multitudinous factors, namely:

  • Network connection failure
  • Abrupt system shutdown due to power failure (dirty shutdown)
  • Bad sectors on the hard disk
  • Errors during synchronization
  • A virus attack

Both these hardware and software reasons forfend the automatic synchronization of OST files with MS Exchange Server. Outlook users are often left gaping helplessly due to loss of paramount data when the OST files are corrupted.

The silver lining in such a situation, is the recovey of all the user data from the OST file in a usable form.
