In Outlook there is a concept of conversation indexes. The original email will have a conversation index like so:
01017C2A2FF4481FED6C146C98A04E2FDB77CEFE8E239603ED7DE0
According to many google searches a reply appends a datetime stamp to it
01017C2A2FF4481FED6C146C98A04E2FDB77CEFE8E239603ED7DE0800000ABF0
800000ABF0
However none of them tell you how to parse this value.
How would you get a DateTime object from that?
