    Troubleshoot OST file error: “cannot open your default email folders, the file xxxx.ost is not an offline folder file”

    The offline storage table is one of the important MS Outlook data files and used by Exchange Server to allow the users to access their emails and other mailbox items even in the offline mode. User can even create, modify or delete the data in the offline mode, and the relevant changes are then automatically synchronized with the mail server when the internet connectivity is back or available.
     The OST files work as the mirror image of exchange database mailboxes available on the user machine, which works when cache exchange mode is enabled. In simpler term, the OST files are an exact replica of exchange mailboxes stored on the host machine.
    However, user may sometime face inaccessibility issues by throwing an error message like: ‘cannot open your default email folders, the file xxxx.ost is not an offline folder file’. This error message restrict users to access any mailbox data, no matter how many times they try.
    Reasons for the occurrence for this error message:
    1. When offline storage table files (OST) get corrupt or damaged, it is generally not identified by the Outlook and hence MS Outlook does not report about this error
    2. MS Outlook fails to synchronize the offline folders with the associated exchange mailboxes and therefore displays such error.
    3. Communication woes between Exchange Server and Outlook may also result in this error message
    4. Sometimes, virus intrusion or unreliable internet connectivity may be a reason for this error
    In such critical cases, the aftermaths of this error message may even lead to information lapse or may affect the complete mailbox data to become inaccessible to open the Outlook mailbox.
