To convert OST files to PST for use in Outlook 365, start by installing the SysInfo OST to PST Converter. Launch the tool and load the OST files you want to convert. The software gives you a full preview of all the emails, contacts, calendars, tasks, and attachments in your OST files. Next, select PST as the desired output format and choose the folder where you want to save the converted file.

To convert OST to PST in Outlook 365, use one of these methods:
Manual Export (if OST is connected to Exchange):
Open Outlook > File > Open & Export > Import/Export > Export to PST.
Third-Party Tools (if OST is orphaned/corrupted):
Use tools like SysTools OST to PST Converter or Stellar Converter for OST.
Reconnect OST (if Exchange is accessible):
Re-add the account to sync data, then export to PST.
Note: Backup OST files before conversion.

Converting an OST to a PST file in Outlook 365 can be somewhat tricky but is quite possible. As I found out for myself, here's how:
Export via Outlook: This is the easiest way to convert an OST file into a PST using the export feature in Outlook itself. I directly go to File > Open & Export > Import/Export, click "Export to a file," and then select "Outlook Data File (.pst)". Further, I am allowed to choose those folders that I want to export and save as a PST file.
