This operation resembles how a folder works with the messages in it. As soon as the recipient table is validated to guarantee recipients that are formatted correctly, ScanPST makes any changes that are required to synchronize these valid recipient table contents to the recipient properties on the message.

ScanPST also guarantees that the message's parent folder refers to a valid folder. The following message properties are checked to make sure that they follow valid data formats:. ScanPST checks that this property exists. If the property does not exist, it is set to IPM. If the submit flags indicate that the message is marked as submitted, this property must exist.

If the submit flags do not indicate that the message is marked as submitted, the time is set to Now. This property must exist. If the property is not present, the time is set to Now. Sizes are recalculated and compared to stored values. If sizes differ by some delta, the calculated value is written. No validation is explicitly done on body-related properties or on subject-related properties, except the implicit low-level validation that this article discusses earlier. The recipient display properties are changed to be consistent with the recovered recipient table.
