However, it is essential that the area has to be configured with an Outlook Exchange Server in order to have a proper synchronization. Unlike all other file types an OST file also gets corrupted. This corruption may hinder the process of conversion. OST file is an important file because it allows a user to work offline when Exchange Server is physically not present. OST file gets damaged mainly because of OST file corruption or synchronization error. There are many other reasons which lead to the OST file corruption and prevent the conversion process from systematic execution. Before knowing the reasons for OST file corruption, it is essential to know the necessity for converting OST file to PST file. Basically, there are two reasons under which it is necessary to convert OST file to PST file. The reasons responsible for conversion are as follows:

Retrieving data in case of emergency from a user profile: In case if you are absent for a day from your work and in that scenario if your boss or fellow colleagues want to retrieve any important data stored in your Outlook profile, then in that case, they have to convert OST file which is a replica of your main PST file into new PST file so that they can easily access emails and other required information. Another scenario of an emergency is when a particular employee leaves forever in that situation it is very essential to make use of Mailbox to PST file converter in order to access all the critical information.

Necessary to convert in order to accommodate all the files within a specific size limit: - On a yearly basis it is very much essential that you should check the size limit of your Outlook profile in order to accommodate every single file within a specific size limit. Once it exceeds the default size limit then there are more chances of file corruption. Therefore, in order to avoid such circumstances, it is necessary that you should convert OST files to PST files so that you can retain more space for storing all other critical information.

The reasons for OST file corruption which can hamper the conversion process are as follows:

Power surge and abruptly shutdown: - Power helps to keep your system in active mode. If you face a sudden power surge, your system will shut down abruptly. By this, your conversion process will get affected, and it will pause in between of the process. Your OST file may get corrupted because of this, and you may not be able to re-start your conversion process all over again. Power failure and sudden shut down affects the harmonization of the conversion process.

Network problem: - Network plays an important role in synchronizing conversion process in a very systematic manner. Fluctuation of the connection or network error can hinder the conversion process. Due to this your OST file gets corrupted, and you may not be able to access it until and unless you repair it. Thus, in this case, it is essential that you must use the best OST to PST file conversion tool.

File system error: - File system error can damage the file structure severely. Because of this error, some parts of the original OST file will be lost or overwritten by garbage data, which makes the final salvaged OST file incomplete.

Outlook OST file exceeding specific size limit: Your OST file may get corrupted if it exceeds the specific size limit of MS Outlook. For example; if you are using Microsoft Outlook 2000 and your file size exceeds more than 2GB then there are chances that your file may get corrupted. Likewise, MS Outlook 2003 has 20 GB size limit and MS Outlook 2007 and 2010 has 50 GB size limit.

Therefore, if you want to execute the smooth process of OST to PST file conversion, it is necessary that you protect all your OST files from above-mentioned scenarios.
