OST is an Outlook Data File created by Microsoft Outlook that allows you to work offline when you are not connecting to the internet. When you connect to the internet, it will synchronize the changes with the help of the Exchange Server. An OST file stores a copy of your mailbox items, like emails, contacts, calendars, tasks, etc. 

However, OST file corruption is a common issue when any unfavorable problems arise on the system, like unexpected power cuts, a bad internet connection, etc., which many Outlook users face. In the following part, we have discussed all the possible reasons related to OST File corruption issues.

For example synchronization process is going on suddenly, and a power cut is due to an unexpected power failure. It may affect the .ost file. An unpredicted power outage can cause hardware failure and sometimes even a hard disk crash.

An Outlook file has a definite size limit. It means it can’t store the mailbox data more than its storage limit.

According to the experts, you should convert OST to PST as a backup on your local drive. So that your business information remains secure.

So you can fix your network connections to avoid file corruption issues.

A hard disk is the main drive where almost all data is stored. Any issue or error in the hard disk drive can put all your data at high risk of corruption.
