Symptom:


Ingest an Outlook email or archive that contains a "blank" date field.  After exporting from Forensic Tools, the date shows as 1/1/4501.


Cause:   


According to Microsoft, the date field can never be stored as blank or NULL.  If no value is written to the field, the value will default to 1/1/4501.
