Repair corrupt OST files with a proficient email migration utility

MS exchange server and MS outlook programs are used in several business enterprises for email communication. In an MS exchange work environment, several outlook user accounts are created on an exchange server. These outlook accounts are meant for both internal and external email communication. When connectivity between the MS outlook and exchange server is broken, all email folders of the outlook mailbox are stored in an offline storage table or OST file. OST file is saved outside the exchange server and a temporary folder unlike outlook PST file. It allows the outlook users to use their mailboxes in offline mode. All work done by outlook users in offline mode gets stored in OST files. The OST files synchronize with exchange domain server, soon after resumption of internet services.

Like outlook PST files, OST files also face several corruption issues. Corruption in OST file arises due to accidental deletion of outlook accounts from exchange server, virus attacks and many more. These factors halt OST synchronization with MS exchange and may results loss of important emails.

All Microsoft outlook versions are equipped with inbox repair tool called scanpst.exe. You can run the scanpst.exe to repair inaccessible OST and PST files of MS outlook. Scanpst.exe can be run on corrupt OST or PST file. It retrieves emails and attachments from the inaccessible OST files and saves in new PST files. Scanpst also creates backup file for each repaired PST or OST file. However using scanpst.exe to repair several inaccessible exchange mailboxes is time consuming. Moreover, the inbuilt repair tool fails to recover emails from badly corrupted OST files.

To fix the different corruption issues of OST files, one should use a smart party OST to PST migration utility. OST to PST migration utility is capable of repairing several corrupt OST files of exchange server in few minutes. The software retrieves entire items from the corrupt OST files and exports in new PST files of MS outlook.
