Export mailbox as a PST file

Login to Outlook with the Exchange account that was used to create the OST files. And to export the OST mailboxes to PST, follow the simple procedure as given here:

Note: You have the option to include subfolders as well.

1. Go to Files >Open & Export and click Import & Export.
2. Select Export to a file; then click Next.
3. Select the second option—Outlook Data File (.pst)—and click Next.
4. Select the folder(s) which you want to export and click Next.
5. Browse the location where you want to save the new PST files and choose an option regarding the duplicate items.

Note: There is an optional choice to provide a password to the PST file, but you can easily move ahead without choosing it.

One of the best tools to convert Outlook OST to PST is the Microsoft OST to PST Converter. It converts the OST files to various email clients in a risk-free manner with data integrity. It let you import corrupted or damaged OST files without any data alteration. The folders' structure also retains throughout the whole conversion process. If you want to import OST files to other file formats or email clients, I would suggest using this utility for the best output.
