If you’ve ever had an OST file that won’t open because Outlook isn’t installed or the profile is gone, this article explains what to do. It talks about why OST files become inaccessible and how you can safely fix access problems. One reliable way is using the MSOutlookHelp OST to PST Converter, which lets you convert OST to PST even when Outlook isn’t available. This tool keeps all your mailbox data intact, including emails, contacts and calendars, so nothing gets lost. It also supports selective conversion, meaning you can choose specific folders or items rather than converting the whole file, which makes the process faster and cleaner.
