When to Use Stellar PST Repair Software?

Need to fix corruption in large-sized PST file?

PST files can grow several GBs in size with routine usage of Outlook and backing up of mailbox data. Such large PST files lead to issues like Outlook freezing & crash, and ultimately get corrupted. Stellar PST repair software provides a fast and effective solution to repair corruption in large PST files.

Unable to repair a PST by using scanpst.exe?

Scanpst.exe is designed to repair inconsistencies in the data structure. But, these data structures are not aware of the organization of messages & calendar in the PST file. So, a PST file repaired with scanpst.exe may have a modified data structure. Stellar Repair for Outlook repairs the PST file and extracts mailbox data in original, intact form.

Need to view Outlook emails in other applications?

‘You may want to access the emails extracted from PST file without installing the Outlook client. Using Stellar PST repair software, you can export the repaired mailbox data in other file formats such as HTML, EML, MSG, RTF, and PDF and access it without Outlook.
