How to Recover Corrupt OST and Save It as PST?

rohit1208

Microsoft Outlook stores offline mailbox data in OST files. Sometimes these files become corrupted due to abrupt shutdowns, Outlook crashes, synchronization errors, or oversized mailbox data. As a result, users may face issues like inaccessible emails, Outlook startup errors, or missing mailbox items.

TL;DR: A corrupt OST file can prevent users from accessing mailbox data in Microsoft Outlook. You can try Outlook’s built-in repair utility, but for severe corruption, using the Cigati OST Recovery Tool is a faster and more reliable solution to recover emails, contacts, calendars, and save them into PST format without data loss.

Common Signs of OST Corruption

• Outlook fails to open OST file
• Synchronization issues with Exchange Server
• Missing emails or mailbox folders
