OST
file is the offline data file of an outlook mailbox connected with an
exchange domain server. OST file is created within an exchange mail
environment and it allows the outlook users of exchange server to use
their accounts in offline period. Changes made by the outlook users
during offline period are recorded in OST files. The changes of OST
files are transferred to the Outlook
PST files, when link between MS outlook and exchange mail server is
re-established.
However,
many times data transfer from OST to exchange mail server fails.
There may be several factors behind non-synchronization of OST with
exchange domain network such as:
- Error
in networking drive: Changes in OST file
fail to synchronize with exchange mail server, due to problem in
network drive. The problem may arise due to broken LAN or WAN cables
and damaged Ethernet ports of window system.
- Corrupt
Storage Media: OST files are stored locally
in different client computers of exchange server. When hard disk of
a client computer are physically damaged or have multiple bad
sectors, all files including OST file stored in it also become
corrupt.
- Unexpected
System shutdown: OST file becomes
inaccessible due to accidental shutdown of the computer system. The
window program may be forced to shut down due to
poor backup by UPS system, power cut or
hardware problem.
- Virus
and spyware codes: Malicious programs can
enter in the exchange domain server from external sources like pen
drive and floppy drive. These programs block the OST files for use.
Outlook
users cannot open their personal mailboxes due to OST file
corruption. It is very important to know the exact cause of OST file
corruption before troubleshooting the issue. If OST file is damaged
due to certain virus code, you should run an effective antivirus
program on the corrupt file. This will clean your OST file from
infection.
Microsoft
has added free email recovery tool scanpst.exe in outlook program.
You can find the scanpst.exe utility in MS office folder of your
computer drive. Scanpst.exe can repairs both PST file and OST file
of MS outlook. The software successfully fixes minor corruption
issues of PST files such as oversized PST file and CRC errors.
However,
scanpst.exe is not capable of restoring a batch of OST files. You
must run a third party OST to PST tool to retrieve emails of
inaccessible outlook mailboxes. OST file conversion software
successfully fixes both minor and severe corruption issues of OST
files. The software is capable of retrieving all emails and
attachments from the damaged OST file. OST file conversion utility
sends the retrieve emails of corrupt outlook mailbox in a new PST,
MSG, EML or DBX file.
Kernel for OST to PST
file conversion supports recovery of both UNICODE and ANSI emails
from the inaccessible OST files of exchange server. It supports
different versions of exchange mail server, MS outlook and outlook
express. OST file conversion utility can successfully run on Window
versions 98, 2000, XP, 2003, 7 and Vista. Before, buying an email
recovery program, I advice the users to evaluate the software.
