OST files are Outlook offline data files automatically created by MS Outlook email client for offline data access and backup. This file syncs and stores all emails, mailboxes, contacts, calendars, tasks, notes, journals, etc from your email account.

If you have one or more OST files from an old computer and want to access it another computer with the latest version of Outlook 2019, then you need to convert OST to PST file because there is not any way to directly import OST file in any version of MS Outlook application.

If you could able to access your Outlook account then, OST file automatically recreated locally in your new system. However, your credential of the account should be the same. As we know that OST file cannot be migrated from one system another so for using old OST file data, you must need to convert it in PST file; Then you can import PST file in your new profile.

You can take help from the third party software like Stellar Converter for OST. With the help of this software, you can quickly access mailbox items by converting the OST file into the PST file format. After that through “ Import & Export” wizard, you can import PST file into new account.
Hope this helps.
