What steps should I take to fix corrupt OST files in Outlook 2025?

[kabirsaini]

Users have several methods available to repair a corrupted OST file, depending on the severity of the issue. To begin with, always ensure a stable internet connection before connecting Outlook to the Exchange server, as unstable connectivity can lead to file corruption.


For minor OST file issues, Microsoft provides the Inbox Repair Tool (SCANPST.EXE). This built-in utility can fix basic corruption in both OST and PST files. Simply locate SCANPST.EXE in your Outlook installation folder and follow the on-screen instructions to scan and repair the file.


However, for more severely damaged OST files, a more robust solution is often required. In such cases, using specialized third-party software is the most effective approach. One highly recommended tool is the GoldyTools OST Recovery Software.


This advanced utility is trusted for its ability to repair deeply corrupted OST files while preserving all mailbox items, including emails, attachments, contacts, calendars, and more. Its user-friendly interface and powerful recovery algorithms make it an ideal choice for both technical and non-technical users seeking a fast, reliable OST file recovery solution.

You’re dealing with corrupt OST files in Outlook 2025; here are some easy steps to try. First, close Outlook and restart your computer. Then, use the built-in Inbox Repair Tool you can find in your Outlook installation folder. This tool can fix minor issues in OST files. That doesn’t work, delete the corrupt OST file and let Outlook rebuild it when you reopen the software. But it is a tricky and time-wasting way; all users can use it, and corrupt OST files can't be properly repaired. I suggest the best TrustVare OST to PST Converter Software, which is easy to use for all users without any hassle. It helps recover emails, contacts, attachments, and other data from OST files into PST format so you can easily access them in Outlook again and fix all OST data. These steps should help get your Outlook data back safely. It supports all Windows OS and MS Outlook. It provides a demo version for free, so all users can try it.
