I have our legal team questioning whether documents are getting deduplicated after several custodian evault containers are collected, then processed in Clearwell. An example is that there are two separate documents in the corpus even though they are the same email message. One appears as being a message from Custodian A's sent items - Custodian A is the sender. The second appears as a message in Custodian B's inbox - Custodian B is the recipient. In my mind, these are not identical therefore not deduplicated because one document is from a sender and the second document is from the recipient. Is this assumption correct?
This is further complicated by the sender's email address being identified as username@internal_domain instead of username@<mycompanyname>.com. Does the interpretation of the email address impact whether these messages are identified as unique therefore not deduplicated?
