The Inbox Repair Tool (ScanPST) opens, appears to complete the file repair and yet, the error message won’t go away.
If you see this message once, it’s likely the data file needs repaired. If it comes up multiple times in a row, it may be a bug in Office Version 2005 Build 12827.20268 or higher.
Microsoft has a registry fix available for the bug
