Many Outlook users face the challenge of accessing data from OST files, especially when the original mailbox is unavailable or when migrating to a new email client. OST files cannot be opened directly in Outlook without the associated account, creating inconvenience for users who need their emails, contacts, or calendars. The MSOutlookHelp OST to PST Converter is a reliable tool designed to convert OST files into PST format safely. It supports email, contacts, calendars, tasks, journals, and notes, and allows bulk conversion, date-filtered export, and migration to Office 365 or other email clients. This tool preserves data integrity, removes duplicates, and enables saving emails in multiple formats, improving efficiency and organization. It’s user-friendly, requires no Outlook installation, and offers a preview of OST data before conversion, making it accessible for all users.
