Thanks to the Exchange Server's offline Outlook Data Files, users can access their mail even when a mail server is unavailable thanks to OST data or offline storage tables. Most Outlook users have probably worked with OST files to store their emails. They are an identical replica of the Outlook Mailbox's content.
When Outlook is connected to the Microsoft Exchange Server, it immediately synchronizes modifications made to offline OST files. However, OST file corruption might occasionally result in errors or prevent files from opening.
When trying to launch Microsoft Outlook, you may see this error message:
In the file C:\Document and Settings\Username\Local Settings\Application Data\Microsoft\Outlook\outlook.ost, an error has been found.
Causes of OST File Corrupted
