I am attempting to repair an Outlook 2007 data file with ScanPST. I ran it 3 consecutive times, detecting errors and repairing them. I intended to continue running Scanpst until it found no errors, which is a practice that has yielded positive results in the past. However, on the 4th run Scanpst reported errors found, but there was no option to repair the file, and the backup file option was grayed out. The only available option was "OK" which appears to simply exit ScanPST without repairing anything.
I shutdown and rebooted, exited iTunes, Google calendar, anything I though might access the data file to no avail. Suggestions appreciated.
