Resolve the error encountered in synchronizing the OST mailbox due to 2 GB file size limitation

When trying to set-up a connection with MS Exchange server but it starts showing up problems then the situation could be fishy. The connection error, most of the times, is the consequence of synchronization problem, network issues, mailbox corruption, etc. Yet another situation which could be the reason of synchronization error of OST mailbox with the exchange server could be oversized OST.

Let us consider a real-life situation where you try to set up the connection with MS Exchange server, unaware of the fact that the OST has exceeded the 2 GB file size limit. As a result, the following error is encountered:

Errors in background synchronization

Within the Deleted items folder of Microsoft Outlook Express, the synchronization log consists of the following entries:

• 15:19:28 Synchronizing Mailbox
• 15:19:28 Synchronizing Folder 'Outlook Security Setting'
• 15:19:28 Error synchronizing folder

How to eliminate corruption issues of the OST file

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.

Ways to resolve corruption issues of exchange OST files

MS outlook is a popular text messaging tool used for sending and receiving text messages or emails. It has several user friendly features like large mailbox size, import export management, fast delivery of emails, multiple file attachment supports, contacts and many more. You can link MS outlook with POP3/IMAP email server such as MS exchange. One can also connect his outlook mailbox directly with internet. MS exchange server provides interface to all outlook users of a domain network. Email records of the outlook user account are stored in two files i.e., OST and PST files. OST or offline storage table is a temporary file that stores all emails of single outlook user account. When internet services in outlook mailbox is interrupted or lost, all emails of that account is saved in an offline file or OST file. When MS outlook is reconnected with internet, all mail communication of the outlook user during offline period is transferred from OST to PST file.

However, many factors prevent OST files to send emails in outlook PST files. These factors are:

• Intrusion of virus and spyware code through exchange server
• slow internet connection
• Hard disk error
• Fault in networking cable
• Crash of exchange server

OST file may be damaged due to any of the above mentioned reasons. When OST files of exchange server become corrupt, all outlook mailboxes stored in these files also become corrupt. In that situation, users shall not be able to use their outlook account. You shall get different error messages while trying to open your outlook mailbox from the corrupt OST file:

• Cannot open your default email folders. The file xxxx.ost is not an offline folder file

MS outlook program is equipped with inbuilt recovery tool scanpst.exe to repair both PST and OST files. Scanpst.exe is saved in different location of user system. You can find the tool either from the search box of window start menu or through manual search. The inbuilt OST file recovery tool of Outlook will retrieves emails and email folders of outlook mailbox from the corrupt OST file. All retrieved items are saved by the scanpst in new OST file. However, scanpst.exe fails to retrieves emails in its exact form from the corrupt OST files. Earlier versions of the MS outlook restrict the OST and PST file size up to 2 GB only. The OST file recovery tool of MS outlook also fails to repair the oversized OST files. Scanpst.exe is suitable for minor corruption issue of OST and PST file. It cannot be used to fix the corruption of large or several outlook mailboxes.

Another way of OST file recovery is making backup of OST files before corruption using Window backup archive creator or any third party convert OST to PST software. You shall be able to retrieve outlook mailbox items from the backup copy in case loss of original files.

If you don’t have backups of OST files or OST files are severely damaged, then use proficient third party email recovery software. The third party OST to PST utility retrieves emails from the corrupt OST file and saves in PST file.
