Migrating from on-premises Exchange to Office 365 necessitates careful planning and administration. The amount of mailboxes also influences the mailbox migration process (cutover, staged, or hybrid).
Emails in Office 365 are available from anywhere in the world as long as you have internet access. As a result, many Exchange customers prefer to preserve an Office 365 replica of their Exchange mailboxes. One can easily accomplish this by transferring their offline Outlook Data File (OST) to Office 365 accounts. It can get accomplished in a variety of ways.
It's not easy to migrate OST to Office 365. It is a difficult task for novice and non-technical users. Third-party tools get recommended for transferring OST files directly to Office 365. For this, Shoviv Outlook Suite is a useful tool.

It can recover and restore both corrupt and non-corrupt OST/PST files, and export them to a live exchange server, Office 365, and the Outlook profile store. So try this software to migrate OST to Office 365, and the software's free trial version only allows users to process the first 50 items per folder.
