The safest approach to extracting contacts from an OST file is to preview the available records before exporting them. Choose a suitable output format, such as CSV, and save the exported data to a separate destination. Keeping the original OST file unchanged helps preserve the source data while you check the exported contact information.

For this process, Aryson OST to PST Converter lets users load an OST file, preview mailbox items, select the Contacts folder, and export contacts to CSV. It also supports individual contacts and contact groups, allowing users to review the available information before completing the export.

When you need to extract contacts from OST file, check fields such as names, email addresses, phone numbers, and company details. The software also supports exporting emails, calendars, tasks, notes, and attachments in supported formats. Since results depend on the source file, review the exported CSV in a compatible application to confirm that the required contact records are present.
