PST File - Outlook Inbox Repair Tool Can't Repair

We recently enabled folder redirection for a few staff members. After their PST file is migrated to the network share, Outlook can't read it. When we run the Outlook Inbox Repair Tool. We get this error: This data file appears to have been created using a newer version of Microsoft Outlook that this Inbox Repair Tool does not support.

The Office version has not changed on these machines - they are running Office 2013. SCANPST is being ran from these machines as well.

Does anyone have a solution?
