If you only have an Outlook .OST file and cannot open it directly in Microsoft Outlook, there's no simple solution, as OST files are linked to Exchange/IMAP servers and Outlook doesn't open them directly. In such a situation, eSoftTools OST to PST Converter Software offers a highly effective solution. This software scans offline, corrupted, encrypted, or inaccessible OST files and securely converts all emails, contacts, calendars, attachments, and other mailbox items contained within them to PST format, which can be opened directly in MS Outlook. Simply add the OST file to the software, scan and preview the content, and then convert and export it to PST format. You can then access the converted file in Outlook using the "Open Outlook Data File" or import option. Thanks to this tool's user-friendly interface and advanced recovery features, the process of opening an OST file in Outlook becomes quick, secure, and reliable.
