When you use Outlook over a long period of time, you have to deal with various hardware and software issues such as sudden power outages, hardware failure, virus or other malicious attacks. These could result in some corruption in the OST files. So long as the corruption levels are low, by immediately repairing the few messages that are damaged, one can prevent the corruption from getting worse and can continue working with the contents of the file. Damaged messages may give rise to synchronization problems and even make the OST files inaccessible. It is best to repair the files and recover ost data before the damage becomes permanent.
If the OST file you are working with contains some items that are corrupted, you are likely to get error messages while synchronizing the OST file with the mailbox on the Exchange server. It is also possible that some items present in your OST file are not to be found in the mailbox or those present in the mailbox are missing from the OST file, despite a recent synchronization. This indicates that there are some problems in synchronization. Missing items of this nature or problems in synchronization itself suggest very strongly that there is some corruption in the OST files and that it is best to immediately run the OST Integrity Check Tool to recover ost data to the maximum.
Typically, the OST Integrity Check Tool can be used only for OST files. It can carry out a very efficient diagnosis of the OST files and then quickly repair the few damaged messages present in the file to resolve synchronization issues. The way this tool works is as follows. The OST Integrity Check Tool first scans the local OST file and then the mailbox on the server, making a list of all the folders and items in each one of them. Thereby, it tries to identify where the synchronization differences between the mailbox on the Exchange server and the local OST file are. The OST Integrity Check Tool takes care to ensure that no changes are made either in the mailbox during the scan - it simply records the differences found if any. It is up to the user to understand what the discrepancies are and then resolve them. It will also mention the situations that it could not rectify and that require manual resolution. By removing or repairing the damaged messages, it should be possible to have a smooth synchronization between the mailbox and the OST files, thereby enabling the user to recover ost data fully.
When the OST files suffer heavy corruption or if the files are very large, the OST Integrity Check Tool is not able to resolve the problems. It is best to use tools developed specially for this purpose such as Advanced Exchange Recovery from DataNumen, to scan and repair the OST files. Advanced Exchange Recovery uses advanced technologies that help it to scan very heavily corrupted OST files and recover content from very large files as well.
