ISSUE: Corrupted Date/Time Attribute of email

Overview

During migration of items from Enterprise vault some items may fail with following error:

"ErrorPropertyValidationFailure|At least one property failed validation., Can't save invalid object Object Violation. Invalid property = [Calc:StartTime] StartTime. Invalid data for that property = Property: [Calc:StartTime] StartTime, PropertyErrorCode: NotFound, PropertyErrorDescription: .. Constraint violated = Property [Calc:StartTime] StartTime is required and must contain a valid DateTime value...|"

Cause

Items with this error are rejected by Microsoft, because their Date/Time attribute is either missing or is not valid format.
