After a system crash, Outlook was reinstalled but the old profile was no longer available. The only remaining file was a large OST backup, which could not be opened directly. In this situation, the MailsDaddy Free OST Viewer was used to access the data. The software opened the OST file without requiring Outlook installation or Exchange Server connectivity.

Once the file was loaded, the complete mailbox structure appeared, including inbox, sent items, drafts, contacts, and calendar entries. Emails were displayed with full details such as sender, recipient, subject, and timestamps. Attachments were also visible and accessible for preview. Even though the file size was several GB, performance remained stable without freezing.

The tool also includes a search option, which helped in locating specific emails quickly. For users dealing with sudden system failures or missing Outlook profiles, this viewer provides a straightforward way to check OST data without complex recovery steps.
