Reasons for OST file corruption are as follows:

Virus attack: Malware/spyware or virus is the biggest external threat that can damage the file structure of OST files. It makes the OST file inaccessible and unusable for further use. Installing third party application may increases the risk of more virus attack. Once your OST file gets infected with any external threat, then there is more probability that your OST file will get corrupted.

Power surge: Sudden power surge is bad for your system operation. If it happens at the time of creating and managing any OST file, then in that scenario, your OST file may get corrupt. Power surge can affect your system severely and can damage the internal components of CPU. If there is sudden power failure at the time when your OST file is in processing mode, then there are chances that it gets damaged due to its weak file immunity.

File System Error: File system error can corrupt your OST file severely. This error can delete some parts of the original OST file, or it is overwritten by garbage data, which results in incomplete OST file. File system error is also responsible for corrupting the file structure of your OST file due to which your file becomes inaccessible.

Server Failure: Server failure is a major and most important scenario responsible for OST file corruption. Once your server gets damaged due to an internal or external problem then your OST file is likely to get damaged and become orphaned. So, as a result of this you will not be able to synchronize efficiently with MS Exchange Server.

OST File Header Gets Corrupt: Header is an essential component of your OST file. It contains all the necessary information about that particular file like date of file creation, last date of modification, file size, etc. Once your OST file header gets corrupted due to improper system shutdown, power fluctuation or due to interruption during compression process then you will not be able to access any of the information stored in OST file. Your OST file becomes orphaned and handicapped once it gets corrupted.

These issues can be fixed by taking some precautions. Some of the precautionary measures are as mentioned below:

  • Always scan your system in order to delete all the viruses and other external threat in order to protect all your OST files from virus attack.
  • Never shut down your system in between when the conversion process is going on or when the system is in active mode.
  • Avoid renaming the file system from .ost to .pst before converting it by using professional converting software. This activity may restrict you from opening your main OST file.
  • Never store any important data in a damaged data storage device. Check your storage device properly before storing any important data in it.
  • Replace damaged hardware components of your system in order to protect your data from getting corrupted.
