Hello,

Microsoft doesn't provide a tool to convert OST file into PST, but we can try export the data in OST file to PST file within Outlook. To do this, please follow:

1. Open Outlook.

2. Click File > Open & Export > Import/Export

3. In the Import and Export Wizard, click Export to a file, and then click Next.

4. Click Outlook Data File (.pst), and then click Next.

5. Select the account you want to export by clicking the name or email address, such as Mailbox  Anne Weiler or anne@contoso.com. If you want to export everything in your account, including mail, calendar, contacts, tasks, and notes, ensure the Include subfolders box is checked.

6. Click Next.

7. Click Browse to select where to save the Outlook Data File (.pst) and to enter a file name. Click OK to continue.

Hello,

There are many tools available over internet that converts OST file to PST file. One of the tool I had used earlier was http://www.convert-ost-pst.net. I would suggest this tool because it has a very easy interface and their support team was very patient with me and helped me to convert my OST file without much hassle.

Hope this tool helps your friend as well.

You can also use the manual method as recommended by Steve Fan.
